Gary Gregory commented on DBCP-436:
-----------------------------------
Won't fix is OK by me. Drivers can optimize as they see fit. The JDBC I am
writing has to deal with transaction states...
> Avoid executing ROLLBACK when transaction is not active
> -------------------------------------------------------

> Key: DBCP-436
> URL: https://issues.apache.org/jira/browse/DBCP-436
> Project: Commons Dbcp
> Issue Type: Improvement
> Reporter: Michael Mikhulya
> Labels: performance
> Fix For: 2.2
>
>
> {{rollbackOnReturn}} terminates the transaction by calling {{rollback}} on
> the connection as it is returned to the pool.
> It hurts performance.
> I suggest to don't call {{rollback}} if transaction is not active.
> Such improvement is done in HikariCP:
