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, submit a service ticket.

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• Query caching is no longer maintained in the MySQL community.
