    [ https://issues.jboss.org/browse/TEIID-2086?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12714418#comment-12714418 ] 

Steven Hawkins commented on TEIID-2086:
---------------------------------------

If TEIID-2158 is worked, then this should be resolved.  We don't really care about transactionality with the preparedplan cache, so we could also see about relaxing awareness.

> Local result set cache entries are stored in a DefaultCache instance, which has no notion of on-going transactions.  This makes session or less deterministic entries read uncommitted and possibly invalid if populated during a roll-back scenario.
> We should either add transaction aware logic or switch the local cache to a memory based infinispan instance.
