Amazon Redshift will no longer support the use of Python UDFs after June 30, 2026. We will start enforcing it in phases. For more information on the details of Python end of life and migration options, see the blog post that was published on June 30, 2025.

enable_result_cache_for_session

Values (default in bold)

on (true), off (false)

Description

Specifies whether to use query results caching. If enable_result_cache_for_session is on, Amazon Redshift checks for a valid, cached copy of the query results when a query is submitted. If a match is found in the result cache, Amazon Redshift uses the cached results and doesn’t run the query. If enable_result_cache_for_session is off, Amazon Redshift ignores the results cache and runs all queries when they are submitted.

Example

SET enable_result_cache_for_session TO off;
--Amazon Redshift now ignores the results cache
