From its inception, Snowflake has always supported the ANSI standard version of the SQL language. As much as we may enjoy using SQL to manipulate data how cool is it to write in a language based onsomething called lambda calculus? Still, it doesnt quite work when it comes time to write some procedural commands, stepping from one to command to another, particularly in stored procedures. Snowflake SQL allows for stored procedures, certainly, but we have had to define them in another language such asJavaScript. (Admittedly, the list of languages to write stored procedures has been growing and we can also now write stored procedures inPython,Java, andScala.) This was useful, but issuing even the simplest SQL command was often clunky and time-consuming. No more. Since its general release in April, Snowflake has allowed for Stored Procedures to be written in a near-SQL dialect called Snowflake Scripting. This scripting language fits seamlessly with SQL commands and is extended to allow for procedural, conditional and error-handling statements. We will attempt to illustrate some of the main features of Snowflake Scripting through example stored procedures. Lets start with something simple. Based on What We Already Know Snowflake Scripting is a simple extension to the SQL language we already know, gently surrounding commands with aBEGIN-ENDpair. For our first example, we want to have a quick way to delete a small number of temporary tables that we know the names of. -- drop my specific list of tables CREATE OR REPLACE PROCEDURE drop_tmp_tables() RETURNS TEXT LANGUAGE SQL EXECUTE AS CALLER AS BEGIN DROP TABLE "tmp_CUSTOMER"; DROP TABLE "tmp_SALES_ITEM"; DROP TABLE "tmp_PRODUCTS"; RETURN 'Success'; END; --sample call of the procedure -- CALL drop_tmp_tables(); Note: The indentation isnt required, but it helps readability. Its worth noting that the above works in the newer web interfaces for Snowflake (SnowSightorSnowPark), but for theClassicweb interface orSnowSQL(i.e., the command line interface) we need to achieve the same thing by putting the executable commands into a string. -- again, drop my specific list of tables, delimited with $$ CREATE OR REPLACE PROCEDURE drop_tmp_tables() RETURNS TEXT LANGUAGE SQL EXECUTE AS CALLER AS $$ BEGIN DROP TABLE "tmp_CUSTOMER"; DROP TABLE "tmp_SALES_ITEM"; DROP TABLE "tmp_PRODUCTS"; RETURN 'Success'; END; $$; The$$delimiters act as the begin-end markers for a multi-line string. This includes thestring-within-a-string being returned to indicate success. Well use this form going forward, since it is a simple matter to convert it back to the unquoted version. And, in fact, this $$-form also works within the newer interfaces. Variables for Flexibility Snowflake Scripting allows for variables to hold temporary values within the stored procedure, including values passed in as a parameter. In our next example, we pass in such a parameter and use it to make copies (clones) of our three tables; these tables will be named with the passed-in prefix. -- create clones of my list of tables, with a specified prefix CREATE OR REPLACE PROCEDURE clone_my_tables(prefix_str TEXT) RETURNS TEXT LANGUAGE SQL EXECUTE AS CALLER AS $$ DECLARE t1 TEXT default 'CUSTOMER'; t2 TEXT default 'SALES_ITEM'; t3 TEXT default 'PRODUCTS'; newname TEXT; BEGIN newname := '"' || prefix_str || t1 || '"'; CREATE OR REPLACE TABLE IDENTIFIER(:newname) CLONE IDENTIFIER(:t1); newname := '"' || prefix_str || t2 || '"'; CREATE OR REPLACE TABLE IDENTIFIER(:newname) CLONE IDENTIFIER(:t2); newname := '"' || prefix_str || t2 || '"'; CREATE OR REPLACE TABLE IDENTIFIER(:newname) CLONE IDENTIFIER(:t3); RETURN 'Success'; END; $$; In this simple example, you can see a few more of the capabilities of Snowflake Scripting. Specifically, we are able to: Define the variables in the DECLARE section before the BEGIN. Update the newname variable for each table by prepending the prefix. Issue the CREATE TABLE command to clone the newly-named table from the old t

by Brandon Carver, on Jun 30, 2022 3:00:00 AMDecisions. Whether it's paper or plastic, coffee or tea, gas or electric... there's always another decision waiting around the corner. And if you landed on this page, your next decision might just be as important as those previously listed: Snowflake Scripting or JavaScript. For many developers and data engineers, it might be the choice between a familiar road that doesn't quite get you to your destination and an unfamiliar road that gets you all the way there. Regardless, this is a decision you don't have to make alone. Mobilize.Net has been converting SQL scripting languages like PL/SQL, T-SQL, and stored procedures in Teradata to JavaScript embedded in Snowflake SQL for several years now. (In fact, we've blogged about it in the past.) But a couple of months ago, Snowflake published that Snowflake Scripting is now fully available to any Snowflake users. (And we've blogged about a few things you can do with Snowflake Scripting in the past as well.) We've partnered with Snowflake to make it the best that it can be (and will continue to do so...), and that it continues to develop and evolve as more and more users take advantage of writing procedural code using only one language, SQL. But what about migration? You might know that Mobilize.Net and Snowflake have partnered together to develop the best accelerator on the market to Snowflake, SnowConvert. Well, SnowConvert has been automating the incredibly complex conversion of bteq, PL/SQL, and T-SQL to JavaScript embedded in Snowflake SQL for several years now. If SnowConvert can go from sprocs to JavaScript, will it be able to go from sprocs to Snowflake Scripting Procedures? (Dare I say... snowsprocs...? Not to be confused with the incredibly offensive snowcrocs.) Of course. As you may expect, the conversion is much more straightforward. Fear not though, we don't play favorites. With all the flavors of SnowConvert, you will still be able to choose whether you want to output to JavaScript or Snowflake Scripting. Let's take a look at an example that showcases a single element of a conversion that is functionally the same in JavaScript created by SnowConvert and Snowflake Scripting created by SnowConvert, but with a potentially simpler output. I mean, if you're used to writing SQL, the switch to JavaScript could be jarring and often requires a completely different skillset. SQL Procedures to JavaScript and Snowflake Scripting When Mobilize.net SnowConvert evaluates a codebase, the automation tool's goal is to create functional equivalence, not to find the nearest equivalent in the target and give up if there is no near equivalent. As a result, when converting procedures to JavaScript, SnowConvert creates helper classes to create functionality that is not present in the target platform. This can be done by utilizing the full implementation of JavaScript that Snowflake supports. However, when converting SQL procedures in a source platform to SQL procedures in Snowflake (Snowflake Scripting), the conversions are much more straightforward. Let's take a look at what this looks like with a very simple example in Oracle PL/SQL. Oracle PL/SQL Let's take a sample procedure with a RAISE statement as an example. (Note that you can use this code to try this out.) Here's what that could look like in Oracle. -- Oracle test procedure for RAISE conversion. CREATE OR REPLACE PROCEDURE simple_exception_throw_handle(param1 INTEGER) IS my_exception EXCEPTION; my_other_exception EXCEPTION; BEGIN IF param1 > 0 THEN RAISE my_exception; END IF; EXCEPTION WHEN my_exception THEN IF param1 = 1 THEN RAISE; END IF; RAISE my_other_exception; END; --Completes without issue CALL simple_exception_throw_handle(0); --Throws my_exception CALL simple_exception_throw_handle(1); --Throws my_exception, catches then raises second my_other_exception CALL simple_exception_throw_handle(2); Pretty straightforward, right? We have two exceptions (my_exception and my_other_exception

snowflake S3 load data benifites

There are several benefits to loading data into Snowflake from S3 using services like Snowpipe:

  1. Real-time Data Ingestion: Snowpipe enables continuous data ingestion into Snowflake in near real-time. This allows new data from S3 to be immediately available for analysis, ensuring that the analytics reflect the latest information.

  2. Automated Data Loading: Snowpipe automates the data loading process, eliminating the need for manual intervention. This streamlines the data ingestion workflow, reduces the likelihood of errors, and improves operational efficiency.

  3. Scalability: Snowpipe supports the scalable and efficient loading of data intoflake. As the volume of data increases, Snowflake can dynamically allocate resources to handle the growing data ingestion requirements from S3.

  4. Cost-Effective: Snowpipe's serverless architecture and pay-as-you-go model can result in cost savings, as resources are allocated only when data is being ingested. This ensures efficient resource utilization and cost optimization.

  5. Automatic Metadata Management: Snowpipe leverages file-loading metadata to optimize the loading process and prevent redundant data loading. It handles file copies made to S3 and ensures the reliability and accuracy of data processing.

  6. Resilience and Reliability: Snowpipe automates the process of resuming data loading from where it left off in case of disruptions, such network failures or system errors. This enhances the reliability of the data ingestion process.

  7. Immediate Data Availability: Data loaded from S3 via Snowpipe is immediately accessible for analysis and reporting in Snowflake, enabling timely decision-making and insights.

By leveraging Snowpipe for loading data from S3 into Snowflake, organizations can benefit from a seamless, automated, and real-time data ingestion process, supporting agile and data-driven operations.

Snowpipe (a serverless data ingestion service) automates loading data into Snowflake from sources like S3, Google Cloud Storage, and Azure Blob Storage. Snowpipe supports continuous, real-time, or batch loading. This eliminates manual data loading and keeps your data up-to-date.In this article, we will explore Snowpipe capabilities and components. Through hands-on examples, you'll learn how to use Snowpipe to easily and effectively load continuous data into Snowflake. By the end, you will have a solid understanding of how to use Snowpipe to easily and effectively load continuous data into the platform. What is Snowpipe in Snowflake?Snowpipe is a serverless service offered by Snowflake, designed to facilitate rapid and automated data ingestion into Snowflake tables. It allows for immediate data loading from files as soon as they become available in a designated stage. This approach allows for data loading in micro-batches and providing users with access to the data in matter of minutes, eliminating the need for manual execution of COPY statements on a predetermined schedule to load larger batches.To create a Snowpipe, users can use the "CREATE PIPE" syntax to define a database object that contains the COPY INTO command used to load the data. Once created, the Snowpipe exists within the database and can be used to load data in real-time.Snowpipe is especially useful for frequent data ingestion scenarios like data streaming, business analysis, or IoT real-time data processing. Snowpipe does not require the specification of a warehouse, as Snowflake automatically provides the necessary resources for its execution. This serverless approach means that Snowpipe can load data quickly and efficiently without users having to manage or provision additional Snowflake compute resources. But Snowpipe still consumes credits based on ingestion volume, frequency, and processing complexity. Snowpipe leverages file-loading metadata associated with each pipe object to optimize the loading process and eliminate redundant file loading. It provides efficient data ingestion by intelligently handling file copies made by the source team to an S3 bucket and subsequent loading into a Snowflake table within a minute. However, remember that if the same team copies another file to the same bucket, Snowpipe is designed to prevent duplicate loading of both files. This prevents redundant data while ensuring unique files are processed in subsequent runs.The use of file-loading metadata also enables Snowpipe to resume loading data from where it left off in case of disruptions such as network failures or system errors. The metadata ensures that the data ingestion process is efficient and streamlined, reducing the need for manual intervention and improving the reliability and accuracy of data processing.What Are the Best Practices for Loading Data in Snowflake?Here are the essential best practices for Snowflake Snowpipe to optimize your data loading process:1) File Sizing Recommendations:Aim to produce data files that are approximately 100-250 MB (or larger) in size when compressed. This size allows for efficient parallel loading operations.Avoid loading huge files (e.g., 100 GB or larger), as it is not recommended due to potential delays and resource consumption.Aggregate smaller files to minimize processing overhead, and split larger files into smaller ones to distribute the load among compute resources.2) Semi-structured Data Size Limitations:The VARIANT data type has a size limit of 16 MB per individual row.When working with JSON data sets, it is recommended to enable the STRIP_OUTER_ARRAY file format option when using the COPY INTO command to remove the outer array structure and load records into separate table rows.3) Continuous Data Loading Latency:Snowpipe is designed to load new data within a minute after a file notification is sent. However, loading can take longer for really large files or when significant compute resources are required for processing.

Not long ago setting up a data warehouse a central information repository enabling business intelligence and analytics meant purchasing expensive, purpose-built hardware appliances and running a local data center. With the consistent rise in data volume, variety, and velocity, organizations started seeking special solutions to store and process the information tsunami. This demand gave birth to cloud data warehouses that offer flexibility, scalability, and high performance. These days, Snowflake is one of the most popular options that meets these and a lot of other important business requirements.For everyone who is considering Snowflake as a part of their technology stack, this article is a great place to start the journey. Well dive deeper into Snowflake's pros and cons, its unique architecture, and its features to help you decide whether this data warehouse is the right choice for your company. Data warehousing in a nutshell Before we get into Snowflake technology, let's deal with the key concepts of data warehousing for a common understanding.The main idea of any data warehouse (DW) is to integrate data from multiple disjointed sources (e.g., CRMs, OLAP/OLTP databases, enterprise applications, etc.) within a single, centralized location for analytics and reporting. Traditionally, it is a relational database that stores all data in tables and allows users to run SQL (Structured Query Language) queries on it.By the type of deployment, data warehouses can be categorized as on-premise hardware and software are installed locally; cloud-based resources are deployed either in public or private cloud environments; and hybrid cloud the aforementioned capabilities are available under one roof. Depending on the type and capacities of a warehouse, it can become home to structured, semi-structured, or unstructured data. Structured data is highly-organized and commonly exists in a tabular format like Excel files. Unstructured data comes in all forms and shapes from audio files to PDF documents and doesnt have a pre-defined structure. Semi-structured data is somewhere in the middle, meaning it is partially structured but doesn't fit the tabular models of relational databases. Examples are JSON, XML, and Avro files. The data journey from different source systems to a warehouse commonly happens in two ways ETL and ELT. The former extracts and transforms information before loading it into centralized storage while the latter allows for loading data prior to transformation.These are the basics needed to explore the world of Snowflake and how it works. What is Snowflake? Developed in 2012 and officially launched in 2014, Snowflake is a cloud-based data platform provided as a SaaS (Software-as-a-Service) solution with a completely new SQL query engine. As opposed to traditional offerings, Snowflake is a tool natively designed for the public cloud, meaning it cant be run on-premises. The platform provides fast, flexible, and easy-to-use options for data storage, processing, and analysis. Initially built on top of the Amazon Web Services (AWS), Snowflake is also available on Google Cloud and Microsoft Azure. As such, it is considered cloud-agnostic. Modern data pipeline with Snowflake technology as part of it. Source: Snowflake With Snowflake, multiple data workloads can scale independently from one another, serving well for data warehousing, data lakes, data science, data sharing, and data engineering.Snowflake is considered amore serverless offering, meaning as a user you dont have to select, install, configure, or manage any software and hardware (virtual or physical) except for the number and size of compute clusters (more on this later). Also, Snowflake has a unique architecture that can scale up and down based on the requirements and workloads.

Before raw data can be used for analytics, it must first be converted into a form that can be easily queried and placed into a secure, centralized location. The ETL process is designed to accomplish these tasks. While the process used to be time-consuming and cumbersome, the modern ETL pipeline has made faster and easier data processing possible. Implementing a modern ETL process has significant benefits for efficiently building data applications and empowering data-driven decision-making.What is the ETL Process?ETL is an acronym that represents extract, transform, load. During this process, data is gathered from one or more databases or other sources. The data is also cleaned, removing or flagging invalid data, and then transformed into a format thats conducive for analysis. The cleaned and transformed data is then often loaded into a cloud data warehouse or other target data store for analysis.ELT: The Future of Data PipelinesETL pipelines first appeared in the 1970s, and a lot has changed since then. Today, organizations have access to more powerful ways to process and prepare data for use. Modern ELT (extract, load, transform) pipelines have significantly greater capabilities than their predecessors. With ELT, the raw data is extracted from its sources and loaded directly into the target data store. Its then transformed as needed directly within the data store. Here are five benefits of using a modern ELT data pipeline.Provide continuous data processingYesterdays ETL pipelines worked well only with slow-moving, predictable data that fit into neat categories. Common data sources included CRMs, ERPs, and supply chain management (SCM) systems. Data gathered from these sources was typically loaded into an onsite data warehouse and stored in highly structured tables that made it easy to query using SQL and SQL-based tools. Data was typically processed in batches on a predefined schedule, resulting in data that was already hours or days old before it was ready for analysis.Fast forward to today. Organizations collect massive amounts of data generated from many different sources including databases, messaging systems, consumer purchasing behavior, financial transactions, and IoT devices. This data can now be captured in near real time or real time with the modern ELT pipeline, since todays technology is capable of loading, transforming, and analyzing data as its created.Execute with elasticity and agilityTodays ELT pipelines rely on the power of the cloud to rapidly scale computing and storage resources to meet current data processing and analytics demands. Modern cloud data platforms offer near-infinite data processing and storage capabilities. Its unnecessary for organizations to plan in advance to accommodate anticipated surges in resources during periods of more intensive use. Use isolated, independent processing resourcesLegacy ETL pipeline configurations typically used the same computing resources to process multiple workloads. Running workloads in parallel on the same resource negatively impacts performance, resulting in longer wait times. In contrast, modern ELT pipelines separate compute resources into multiple, independent clusters with each workload receiving its own dedicated resources. This setup drastically increases the speed at which data can be processed, transformed, and analyzed. The size and number of clusters can rise and fall instantly to easily accommodate current resource demands.Increase data accessSome data pipelines relied on highly skilled data engineers to build and maintain the complex constellation of external tools required to customize the ETL process to the unique needs of the organization. The resulting IT resource bottlenecks prevented timely access to relevant data, resulting in decisions based on stale data. However, modern and ideal ELT pipelines democratize data access by simplifying data processing, making the process of creating and managing data much less reliant on IT experts. This demo

The Snowflake data platform for data engineering, data preparation, and ETL Snowflake is an outstanding data platform for data warehouse use cases. Did you know that it is also at the top of the class for data engineering? This hands on blog post walks you through some scenarios and examples of using the Snowflake data platform for data preparation and ETL. Overview Did you know that the Snowflake data platform is the perfect fit for ETL, data integration, and data preparation tasks? In this blog post we will give you some hands-on advice on how you can use Snowflake as an ETL engine for data preparation. Lets take this common scenario as an example: Your company has built a data lake on object storage, e.g. S3. The raw data on your data lake requires transformations. Lets say you want to build the features for a predictive model. With Snowflake you can create an external table over your data on S3, apply the transformations for feature engineering and then unload the data back to S3 in Parquet for downstream processing by your data science platform. There couldnt be a better fit than Snowflake for the job. OverviewBenefits of using Snowflake for data engineeringSnowflake for data preparationData set on S3External tables on SnowflakeData preparation with SQLUnload data to ParquetConclusion Benefits of using Snowflake for data engineering Snowflake follows a utility billing model. You only pay for the resources you use. If your ETL job takes 2 minutes to run you only pay for those 2 minutes. If it takes 3 hours you pay for 3 hours. Snowflake can scale your ETL workload across hundreds or even thousands of nodes. This is important because you can meet any SLA as the platform scales linearly for most transformations. Lets assume your ETL job runs for 10 minutes on a cluster with 4 nodes (Medium sized cluster). By doubling the cluster size to 8 nodes you can cut the processing time in half. And the best thing is that you dont pay a cent more as your job now runs in 5 minutes and you only pay for what you use. This is magic. Unlike other platforms, Snowflake scales instantly. You dont have to wait for minutes before your cluster becomes available and your ETL job starts running. Writing code for data transformations on Snowflake is significantly faster than on other platforms. You also dont need expensive engineers with skills in low level programming languages. Just use the power of SQL, the lingua franca of data. I have not yet come across a requirement that can not be met by writing pure SQL. I challenge you to give me an example where SQL cant be used to implement your business logic. The Snowflake data platform is a fully managed service. You dont need any resources to administer or maintain the platform. You can easily spin off sandboxes for data exploration, data discovery, and data science using the zero copy clone feature. This feature can copy Terabytes of data in less than a minute. You dont need to license an expensive point and click ETL tool. Just run your workload directly on Snowflake.I have recently outlined the limitations of point and click tools in a presentation at the Knowledge Gap conference and also written up a blog post. At Sonra we use Apache Airflow together with Snowflake for data warehouse automation. Snowflake supports big data formats such as Parquet, Avro, ORC, which are commonly used in data lakes. Snowflake for data preparation In this scenario we have a data set on our data lake on S3. This data can be accessed by multiple consumers, e.g. Spark for data science and Snowflake for data preparation and data warehousing. Using a Snowflake external table over the data set on S3 will allow us to query the data, run some transformations for data preparation (feature engineering) on Snowflake and then unload the data back to S3 in Parquet. From there it can be consumed by our data scientists using Spark or some other data science platform. In summary: We create an external table over the data set in Sno

For the second post in my continuing series on Snowflake, I wanted to expand on some concepts covered in my JSON post. Last month, I walked you through how to work with JSON in Snowflake and discussed the process Snowflake uses to flatten JSON arrays into a format that can be easily queried. For this post, I want to talk about what happens before we can access the power of Snowflake with ANY data. This week were going to talk about loading data into Snowflake, which due to its cloud nature, requires a different process than standard or legacy database systems. Snowflake supports a handful of file formats, ranging from structured to semi-structured. Layered on top of the file formats are the protocols we can use to bring that data into Snowflake. Since Snowflake has a multi-cloud architecture (Amazon Web Services, Microsoft Azure and a goal of Google Cloud support in the future), we luckily have a few options to get our tables loaded. Im going to spend a bulk of the time today talking about how to perform a simple AWS S3 load. AWS Loading from an AWS S3 bucket is currently the most common way to bring data into Snowflake. The entire database platform was built from the ground up on top of AWS products (EC2 for compute and S3 for storage), so it makes sense that an S3 load seems to be the most popular approach. Loading data into Snowflake from AWS requires a few steps: 1. Build and Fill an S3 Bucket To begin this process, you need to first create an S3 bucket (if youre unfamiliar with this process, look here). Something I really like about the way Snowflake interacts with these S3 buckets is that the bucket can contain any of the supported file formats and Snowflake will allow you to specify what to pull out. Snowflake allows you to specify a file format with the copy command, meaning that whether my project utilizes JSON, CSV, Parquet or a mixture of all three, I can organize my data into a single S3 bucket for each project I am working on. 2. Build Snowflake Table and Load from S3 Now that weve built and filled our bucket with data, we want to bring it into Snowflake. We can go ahead and build the tables we want that data to reside in. Since Snowflake uses standard SQL language, and this is simple enough. One thing that is important to note about the table creation is that if you have semi-structured data, it does not require a dedicated table. You can load structured and semi-structured data into the same table. For my example, I grabbed some JSON that contains Countries and their Country Codes. I also grabbed a CSV containing some detailed information about these countries. After uploading each of these to my S3 bucket, I can begin pulling them into Snowflake to populate this table: 3. Build a Stage In the database segment of the UI, I have a section for Stages. This is where I can build a stage using the UI. As you can see above this is pretty straightforward, I selected S3 because that is where my data currently resides. After selecting S3, I am taken to a menu to give Snowflake the information they need to communicate with my S3 Bucket. The main point of confusion on this menu is the URL textbox. All that you need to insert here is the name of your S3 bucket. Snowflake will use your AWS Key ID and Secret Key to locate the correct AWS account and pull the data. The URL should look something like this: S3://[YOUR BUCKET NAME]/[DIRECTORY IF NEEDED] You can also select at the bottom left-hand of the menu to Show SQL. This is a good way to get an understanding of how to interact with Snowflakes tools programmatically. I tend to prefer building stages in the worksheet, the code looks like this: CREATE STAGE "HCALDER"."TESTINGSCHEMA".LoadingBlog URL = 's3://iw-holt' CREDENTIALS = (AWS_KEY_ID = 'PostingYourKeyontheInternetisBad' AWS_SECRET_KEY = '******************'); 4. Copy Data to Your Table Now that I have a stage built in Snowflake pulling this data into my tables is extremely simple. I built a table that contains 6 columns

Welcome! The Snowflake SQL API is a REST API that you can use to access and update data in a Snowflake database. You can use this API to execute standard queries and most DDL and DML statements. This getting started guide will walk you through executing a SQL statement with the API and retrieving the results. Prerequisites A familiarity with Snowflake A familiarity with SQL What You'll Learn Perform simple queries Manage your deployment (e.g., provision users and roles, create tables, etc.) Submit one SQL statement for execution per API call. Check the status of the execution of a statement. Cancel the execution of a statement. What You'll Need A Snowflake Account with an accessible warehouse, database, schema, and role SnowSQL 1.2.17 or higher Working Key-Pair authentication What You'll Build An execution of a statement using the Snowflake SQL API Head to the SQL API by navigating to your version of the following URL, replacing *account_locator* with the account locator for your own Snowflake account: https://*account_locator*.snowflakecomputing.com/api/v2 Now let's break down the parts of the API before we begin using it. The API consists of the /api/v2/statements/ resource and provides the following endpoints: /api/v2/statements: You'll use this endpoint to submit a SQL statement for execution. /api/v2/statements/*statementHandle*: You'll use this endpoint to check the status of the execution of a statement. /api/v2/statements/*statementHandle*/cancel: You'll use this endpoint to cancel the execution of a statement. In the steps to come, you shall use all these endpoints to familiarize yourself with the API. Limitations of the SQL API It's important to be aware of the limitations that the SQL API currently has. In particular noting that GET and PUT are not supported. In some cases, it might not be clear if Snowflake executed the SQL statement in an API request (e.g., due to a network error or a timeout). You might choose to resubmit the same request to Snowflake again in case Snowflake did not execute the statement. If Snowflake already executed the statement in the initial request and you resubmit the request again, the statement is executed twice. For some types of requests, repeatedly executing the same statement can have unintended consequences (e.g., inserting duplicate data into a table). To prevent Snowflake from executing the same statement twice when you resubmit a request, you can use a request ID to distinguish your request from other requests. Suppose you specify the same request ID in the initial request and in the resubmitted request. In that case, Snowflake does not execute the statement again if the statement has already executed successfully. To specify a request ID, generate a universally unique identifier (UUID) and include this identifier in the requestId query parameter: POST /api/v2/statements?requestId=<UUID> HTTP/1.1 If Snowflake fails to process a request, you can submit the same request again with the same request ID. Using the same request ID indicates to the server that you are submitting the same request again. Now let's move on to additional information you need to include in requests: authentication parameters. When you send a request, the request must include authentication information. There are two options for providing authentication: OAuth and JWT key pair authentication. You can use whichever one you have previously implemented or whichever one you are most comfortable with. This example will be detailing authentication with JWT. If you haven't done so already, make sure you have key pair authentication working with Snowflake already. You can test to make sure you can successfully connect to Snowflake Key Pairs using the following command: $ snowsql -a <account> -u <user> --private-key-path <path to private key> After you've verified you can connect to Snowflake using key-pair authentication, you'll need to generate a JWT token. This JWT token is time limited token which has been signed

Looking for a few different ways to build an APIon top of Snowflake? If so, take a look at our other blog post on the topic, Snowflake API: Comprehensive Guide to 3 Methods With Examples.Are you looking for a way to build a fast, secure API on top of your Snowflake data warehouse? Propel's Serverless Analytics API Platform offers a fast and cost-effective way to create an API on top of your Snowflake data that is secure, performant, and low latency. In this post, we will walk you through the five easy steps to connecting your Snowflake Data Source, syncing your tables, defining Metrics, and querying your API with JavaScript, Python, Java, Go, Ruby, and C#/.NET. Let's get started!Why do you need an API on top of Snowflake?Snowflake typically has the most complete data organizations have. It centralizes data from all the different data silos, whether internal databases or SaaS applications. It is also the right platform to clean and transform your data, making it optimal for visualization and consumption.When using the data internally for employees, you can either query the data directly with SQL or through a BI tool like Looker or Tableau; therefore, you dont typically need an API.You need an API on top of Snowflake when you are building customer-facing web or mobile applications that include:User-facing dashboardsProduct usage and meteringAnalytics APIsEmail ReportingCustomer data sharingThese use cases have unique requirements and require a secure and performant data serving layer with low latency and high concurrency to provide a seamless user experience.What are the requirements for an API on top of Snowflake?When looking to build an API on top of Snowflake to power data applications and features powered by large-scale analytical data, you should consider the following requirements: Low latency Customers expect fast, snappy product experiences. While internal employees may be okay waiting 45 seconds or even minutes for a query to run, this latency is a no-go for customer-facing products where the data analysis is part of the core product experience High concurrency Products need to support thousands or millions of users. Because data products ultimately serve customers rather than employees, they must support a dramatically higher number of concurrent requests than what internal data tools are designed to handle. And they must do so seamlessly and cost-effectively. Cost-effectiveness Data has a fundamental tradeoff between flexibility, cost, and performance. The API should make it easy for users to understand and then make this tradeoff for different use cases. Multi-tenant security layer Each end-user can see only their own data. In SaaS and consumer products, end-users access their own data from web or mobile applications. This requires a multi-tenant security layer for business-to-business or consumer environments, not just employee-centric role-based access control.Querying the warehouse directly from customer-facing applications can be slow, costs can get out of control, and it still requires substantial backend service logic to serve this data securely to the frontend.Does Snowflake have an API?Yes, Snowflake offers a pass-through SQL API. It is a REST API that takes SQL statements and executes them against the data warehouse. It is useful if you want to query SQL over REST, but it does not provide any additional abstraction, optimization, or security features to power secure, performant, low-latency customer-facing applications.How do I build an API on top of Snowflake?To build a performant Snowflake API to power your customer-facing web and mobile apps, you can use Propel, a serverless analytics API platform built on top of Snowflake.Propel provides the cloud infrastructure, scalability, and security required to power data applications at a massive scale while giving you the flexibility to define the metrics you want to query. You can build your first Snowflake API in minutes by following these five easy steps:1

Data ingestion is a critical step in the data processing pipeline, and Snowflake, a leading cloud-based data warehousing platform, offers a plethora of options for ingesting data.In this technical blog post, I'll delve into the complexities of Snowflake's data ingestion strategies, exploring different use cases and dissecting the trade-offs between various methods.Specifically, I'll focus on the COPY function, serverless ingests with Snowpipe and integration with Kafka for streaming data. By dissecting these strategies, I aim to provide readers with a deep understanding of how to optimize data ingestion while maintaining cost-effectiveness and efficiency.Use Case Classification for Enhanced IntuitionChoose... three?When faced with numerous data ingestion options, classification based on use cases can provide a more intuitive approach. Snowflake's extensive capabilities span different scenarios, and by classifying use cases, we can identify optimal ingestion methods. Our primary focus in this discussion is the bulk load process using COPY, serverless ingest with Snowpipe, and integration with Kafka for streaming data.Keeping this in mind, let's start by taking a look at the most common tool used to move data into Snowflake.Bulk Import Strategy with COPYSource: snowflake.comThe bulk import strategy involves utilizing Snowflake's COPY command to load data into the platform. While straightforward, this approach can lead to inefficiencies, especially when dealing with underutilized warehouses. The average cost of data ingested can be prohibitively high due to the constant idle state of the warehouse waiting for periodic data uploads. However, optimizing concurrency and file sizes can mitigate these challenges.Here's how it could look to set up an ingestion pipeline with COPY:-- Creating an external stage CREATE OR REPLACE STAGE my_stage URL = 's3://my-bucket/path' CREDENTIALS = (AWS_KEY_ID = 'your_key_id' AWS_SECRET_KEY = 'your_secret_key'); -- Copy data from the external stage into a table COPY INTO my_table FROM @my_stage/data.csv FILE_FORMAT = (TYPE = CSV); -- Check the copy history SELECT * FROM TABLE(INFORMATION_SCHEMA.COPY_HISTORY(TABLE_NAME => 'my_table')); The first step is to create an external stage, which is a reference to the location of your data in a cloud storage service like Amazon S3.The COPY INTO command is used to copy data from the external stage into a Snowflake table.The FILE_FORMAT specifies the format of the files in the stage (e.g., CSV).The final query checks the copy history to monitor the status of the copy operation.Optimizing COPY-based ingestionWhen utilizing Snowflake's COPY command for batch data loading, you have two main avenues to optimize cost and performance. One is to make sure files being ingested conform to the recommended file size range and the other option is switching to a serverless ingestion workflow with Tasks.Let's dive a bit into how we can make this process less wasteful!File-size optimizationsWhen utilizing Snowflake's COPY command for batch data loading, one of the most significant factors influencing performance is the size of the input files. Achieving optimal COPY performance is intricately tied to preparing files within a specific size range, typically between 100 to 250 megabytes. This range ensures efficient utilization of Snowflake's underlying architecture and minimizes processing overhead.The reason behind this emphasis on file size lies in Snowflake's data-loading mechanism. The COPY command is designed to work efficiently with files that are well-sized, allowing for seamless parallelization and optimized resource allocation. When files fall within the 100 to 250-megabyte range, Snowflake's processing capabilities are harnessed to their fullest potential, resulting in faster data ingestion and query performance.Amazing illustration from www.analytics.todayHowever, achieving perfectly sized files isn't always feasible, especially when dealing with diverse data sources o

Demystifying Data Ingestion in SnowflakeSnowflakes main ingestion techniques can be classified into:Batch LoadingContinuous Data LoadingContinuous Data Ingestion with UpsolverSelecting the Right Ingestion MethodClosing Thoughts In todays digital era, data is the linchpin of business intelligence. Therefore, having expertise in the data ingestion process is invaluable. Snowflake, an industry-leading cloud-based data warehousing platform, offers a spectrum of data ingestion techniques. This article serves as your guide to that subject, shedding light on these diverse methods, dissecting their unique merits, practical applications, and key factors for consideration. Armed with this knowledge, you can identify the technique that best fits your business requirements. Demystifying Data Ingestion in Snowflake Snowflakes flexible framework empowers its users to ingest a myriad of data forms from structured to semi-structured data, encompassing traditional databases to JSON, Avro, or XML files. The capacity to fuse and process these varied data types makes Snowflake a game-changer in the data warehousing landscape. Snowflakes main ingestion techniques can be classified into: Batch Loading Continuous Data Loading Each of these methodologies is distinct in their complexity, processing speed, and compatibility with various data types. Lets delve into the nitty-gritty of each approach. Batch Loading Batch loading is a technique of ingesting data in substantial batches at preset time intervals. This method fits like a glove when you are handling copious data amounts that do not require real-time analysis. Its strength lies in the efficient handling of voluminous data. However, it is not designed for applications demanding instant insights, due to inherent delays between data generation and its readiness for analysis. You can attempt to run your batches more frequently, but you must be aware of the maximum time it takes for the job to run to avoid your jobs overlapping. Realistically, when latency matters, using Snowpipe for continuous loading is a more elegant solution. There are two common ways to implement batch loading in Snowflake. COPY INTO command: This is a push technique whereby you issue a SQL command to load data files directly from a cloud-based stage (like Amazon S3, Google Cloud Storage, or Microsoft Azure Storage) or a local file system in large batches. You can think of this as scripting a manual process into a time-based periodic job. Snowpipe: This native Snowflake data ingestion service immediately loads data as it lands in a cloud-based staging area such as an Amazon S3 or Google Cloud Storage bucket. While its typical use case is continuous, near-real-time loading, Snowpipe can also cater to batch loading requirements. For effective batch loading in Snowflake, consider these best practices: Opt for larger batch sizes: Bigger batches enhance efficiency by reducing the number of separate network transfers and load operations. If you choose Snowpipe, Snowflake recommends 100 MB 250 MB file sizes to balance cost and performance. This is because you accrue a per-file charge on top of the compute costs. Compress your data: Compressed data files consume less network bandwidth and storage, often leading to faster loading times. COPY INTO and Snowpipe natively support a number of common compression standards. Eliminate unnecessary data: Prune data that isnt needed for your analysis before loading. This can greatly reduce the data volume, enhancing efficiency. Leverage parallel loading: If dealing with many files, capitalize on Snowflakes parallel loading support to expedite the loading process. To do this you simply make sure your data warehouse is sufficiently large. Of course, this will drive up cost and beyond a certain size is reached the performance returns will diminish. Continuous Data Loading Unlike batch loading, continuous data loading caters to near real-time data ingestion. It constitutes ingesting data in small, f

how to do the data ingestion in snowflake by step1.2,3

Certainly! Data ingestion into Snowflake can be achieved through various methods such as using SQL commands, Snowpipe, the web interface, or specialized data integration platforms like Hevo Data. Here, I'll outline the steps for two used methods for data ingestion into Snowflake - Using SQL Commands and Using Snowpipe.

Method 1: Using SQL Commands for Data Ingestion in Snowflake

Step 1: Staging the Files

  • Upload the data files to a location where Snowflake can access them, often referred to as "staging your files".
  • Snowflake's internal stages or an external storage location like Amazon S3, Google Cloud Storage, or Microsoft Azure for staging your files.

Step 2: Loading the Data

  • After staging the files, load the data into Snowflake tables using SQL commands in SnowSQL.
  • Specify a running virtual Data Warehouse, which extracts the data from each file and inserts it as rows in the table.

Method 2: Using Snowpipe for Data Ingestion in Snowflake

Step 1: Setting Up Your Stage

  • Create a stage for your data files. This can be an internal stage in Snowflake or an external cloud storage stage like S3, Google Cloud Storage, or Azure.

Step 2: Creating A Pipe

  • Create a pipe, which is a named object in Snowflake that holds a COPY statement. The COPY statement specifies where Snowpipe can find your data and which target table to load it into.

Step 3: Detecting Staged Files

  • Configure Snowpipe to detect new files staged in your named stage or external cloud storage location.

Step 4: Continuous Data Loading

  • Once everything is set up, Snowpipe will continuously load data in near real-time as new files become available in your stage.

These steps outline the basic process for data ingestion using SQL Commands and Snowpipe in Snowflake. Depending on your specific requirements and the volume of data, you may choose one method over the other for loading data into Snowflake.

Please note that these are simplified steps, and the actual implementation may involve additional considerations and configurations based on your specific case and data sources.
