DB Access Module for MySQL User’s Guide : Chapter 2 Technical Information : Caching
Caching
This section describes inserter and reader caching.
Inserter Caching
Inserter caching is not supported in this version of the DB Access Module for MySQL.
Reader Caching
Reader caching is fully supported by the DB Access Module for MySQL.
Increasing the cache parameter when producing an RWDBReader increases the number of rows fetched at a time, which can improve performance.
