> Cache ResultObjectProvider data to improve query performance
> ------------------------------------------------------------
>
> Key: OPENJPA-703

> Profiling indicated that JDBCStoreQuery.populateSelect consumes a significant
> amount of CPU, and is executed every time a query is run. While, in fact, the
> actual PreparedStatement is created and run only in QueryImpl.toResult. It
> seems like the returned ResultObjectProvider from JDBCStoreQuery.executeQuery
> can be at least partially cached, or even cached in its entirety (provided
> care is taken with the context parameters).
> It seems like such an improvement would significantly improve query
> performance.
