Amazon Redshift, a fully-managed cloud data warehouse, now supports Lambda user-defined functions (UDFs) enabling you to use an AWS Lambda function as a UDF in Amazon Redshift . This functionality enables you to write custom extensions for your SQL query to achieve tighter integration with other services or third-party products. For example, you can write Lambda UDFs to enable external tokenization of data by integrating with vendors like Protegrity , or access other services such as Amazon DynamoDB or Amazon SageMaker in your Redshift query.
