[jira] [Commented] (DERBY-5083) Document automatic update and creation of index cardinality statistics (istat)

["Kim Haase (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DERBY-5083?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13160092#comment-13160092 ] 

Kim Haase commented on DERBY-5083:
----------------------------------

10.9 would be a good time to document the two properties listed in the 10.8 release notes:

derby.storage.indexStats.auto
derby.storage.indexStats.log

It's now time to update the Tuning Derby topic "When cardinality statistics are automatically updated" and correct any other outdated information in this manual.

If any users see the need for further documentation of this feature, please feel free to comment further on this issue.

> Documentation is needed for the automatic index statistics feature (DERBY-4934). It appears that a change is needed to the Tuning Guide topic "When cardinality statistics are automatically updated", at least.
