Subject [jira] Commented: (OPENJPA-924) Cache Finder Query for performance enhancement
Date Wed, 07 Jul 2010 14:54:49 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-924?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12885961#action_12885961

Rick Curtis commented on OPENJPA-924:
-------------------------------------

I know this comment is way after the fact, but would it be possible to get at least a little
bit of documentation for this feature? 

In OPENJPA-1717 I'm documenting a change in behavior for a feature that hasn't been documented...

> find() operation can result into execution of database query. Performance can be improved
by caching the generated query for reuse. The purpose of cache is similar to JPQL query cache
[1], but the implementation strategy is different. Because the pathways to execute a finder
query is somewhat different than that of a JPQL query.
