Amazon Redshift increases performance for new queries in dashboards and ETL workloads by up to 7x

Amazon Redshift improves the performance of BI dashboards and ETL workloads by speeding up new queries by up to 7x. This significantly improves the response times of low-latency SQL queries, such as those used in near real-time analytics applications, BI dashboards, ETL pipelines, and autonomous, goal-seeking AI agents. Customers experience substantially faster query response times as Redshift accelerates the process of preparing the SQL query for execution. Queries start faster and return results quicker. This improvement is automatically enabled at no additional cost.

To deliver this major improvement, Redshift added a new optimization to query compilation where new queries are processed immediately using composition. Composition is a technique that generates a lightweight arrangement of pre-existing logic while simultaneously creating highly optimized, query-specific code that is compiled and executed across available compute resources to further boost performance. Composition removes compilation from the critical path of query execution and provides immediate execution while compilation proceeds in the background. With this optimization, new queries processed by Redshift start faster and deliver performance consistent with subsequent runs.

This optimization is enabled by default for any SQL query across all provisioned clusters and serverless workgroups, in all commercial AWS Regions where Amazon Redshift operates. It is available on the Redshift current track with other tracks following in upcoming patch releases. No action is required from customers to benefit from this enhancement, and it is free of charge.
