Redshift is an award-winning, production ready GPU renderer for fast 3D rendering and is the world's first fully GPU-accelerated biased renderer. But that’s quite a lot! For example, an authorized UDF can compute an aggregation over data or look up a table value and use that value in a computation. This repository contains SQL for many helpful Redshift UDFs, and the scripts for generating and testing those UDFs. Python UDFs allow you to extend Amazon Redshift SQL with Python’s rich library of packages. This function uses pyaes module to encrypt data using AES encrypt and decrypt functions. You can visually build the import query or use any SQL supported by the driver. You can include more powerful operations in the AWS Lambda function such as accessing storage or network resources, which will allow you to integrate with external services.
