Subject [jira] Commented: (DERBY-2487) Enhance Derby with EXPLAIN Functionality
Date Fri, 06 Feb 2009 15:59:59 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2487?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12671174#action_12671174

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

I'm becoming more familiar with the patch, which is good.

For the next step, I'm thinking about starting to work on some
draft documentation, as I think the process of drafting documentation
will help me clarify some of the details of the patch. I think that the
documentation should include:
 - an overview of what this feature is, how it can help you, and how it works
 - reference material on the new system procedures
 - reference material on the new system catalogs
 - a number of examples of how to use the feature

than they`re getting with the current RuntimeStatistics facility. This extension is based
on the RuntimeStatistics/ResultSetStatistics functions / classes.
