["Kristian Waagan (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DERBY-4771?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12931011#action_12931011 ] 

Kristian Waagan commented on DERBY-4771:
----------------------------------------

The properties have been changed, and are now:
derby.storage.indexStats.auto=*true*|false
derby.storage.indexStats.log=true|*false*
derby.storage.indexStats.trace=*off*|dblog|stdout|both

It may be wise to change the log property default to true, at least as we test the feature.
