Data transformation and combination: If your applications frequently need several queries to get their information, or need to transform data into another format, consider doing this work in a stored procedure.However, you can put reads and writes behind stored procedures, applying the same business logic regardless of which application or user is working with the data. Business logic: Business logic usually lives in applications, not the database.Think of this as your last line of defense to catch errors missed at the application layer. Data validation: A stored procedure that saves data can have safeguards to ensure it only stores valid data.Maintainability: It's easier to manage a stored procedure on the database server than to maintain a series of queries in the application code.Access control: You can grant users permission to execute a stored procedure that retrieves or updates specific fields, without giving full access to underlying tables.That way, you don't have to send it across the wire every time you want to use it. Encapsulation: If your application has complex or frequently-used queries, you can encapsulate it into a stored procedure that accepts a few parameters.Using stored procedures has several benefits: That way, you can easily reuse the same series of instructions. Why Use Stored Procedures?Ī stored procedure is a user-defined routine that’s stored in your database and executed by external applications. All you need to follow along is some basic SQL or programming experience. #Redshift documentation how toTo help you get started, this article shows you how to create and call stored procedures in Amazon Redshift. #Redshift documentation manualIn the latter case, Amazon’s Schema Conversion Tool (SCT) can automatically translate your stored procedures, reducing manual effort during migrations. Alternatively, you can import and translate existing stored procedures living in other warehouses (such as a Microsoft SQL server). The introduction of Amazon Redshift ML allows users to run AI/ML workflow within Redshift itself, eliminating the need for external executions using simple SQL statements.īy utilizing stored procedures within Amazon Redshift, you can efficiently manage a data warehouse and reduce query times. Supported file formats include Parquet, JSON, ORC, Avro, and connecting with Hudi. With Amazon Redshift, you can use real-time analytics and artificial intelligence/machine learning (AI/ML) use cases without re-architecture, as the warehouse is both fully integrated with your existing data warehouse and other specialized data stores, such as Amazon Aurora. Amazon Redshift is a specialized data warehouse that allows users to run unified analytics using a lakehouse architecture.
