Subject [jira] [Commented] (OPENJPA-2220) Persistent field fetching statistic tool
Date Tue, 26 Jun 2012 18:35:44 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-2220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13401590#comment-13401590

Rick Curtis commented on OPENJPA-2220:
--------------------------------------

> A nit: to ...
Nice catch on the isXXXX.

> Several useful tools in the past has been floating around. Please open a separate discussion
thread on how best we could organize our tools and ensure that they reach the users. 
I thought we came the consensus that if the tool has a dependency on a version of the runtime,
it needs to live with the runtime code?. If it has no runtime dependency, it would live in
the seperate openjpa-tools repository?

> This task is to create a  statistic tool which monitors the persistent fields fetching
and finds out the fields which are never accessed. Based on the statistic data, user can set
the field access type to LAZY to improve the performance by eliminating the data loading and
processing time.
