Subject [jira] Commented: (DERBY-2487) Enhance Derby with EXPLAIN Functionality
Date Tue, 17 Feb 2009 01:14:59 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2487?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12674083#action_12674083
] 

Bryan Pendleton commented on DERBY-2487:
----------------------------------------

Brief status update:
 - I've been in contact with Felix Beyer, and we're trying to get the ICLA filed
 - I've made good progress on drafting docs, and on writing some new tests,
   don't have any patches to post yet, but hopefully soon.
 - while writing tests, I found an unrelated issue (I think) in DataValueFactory,
   and will file a separate issue to track that problem

> This enhancement extends Derby with EXPLAIN functions. Users want to have more feedback
than they`re getting with the current RuntimeStatistics facility. This extension is based
on the RuntimeStatistics/ResultSetStatistics functions / classes.
