How Do I Enable Query Caching for My RDS for MySQL Instance?
Parameters related to query caching cannot be set on the console. To enable query caching, contact technical support.
You are not advised to enable query caching because:
- Query caching helps improve query speed only when you frequently access the same SQL statement, but consumes additional resources and reduces the SQL execution speed in other scenarios.
- Function test results show that the query speed of an instance without enabling query caching is faster than that when this function is enabled.
- Query caching is no longer maintained in the MySQL community.
