[jira] [Commented] (HBASE-11054) Create new hook in StoreScanner to
help user creating his own delete tracker
[ https://issues.apache.org/jira/browse/HBASE-11054?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13996448#comment-13996448 ]
Nicolas Liochon commented on HBASE-11054:
-----------------------------------------
This changes the interface of the RegionObserver in 0.98.2 vs 0.98.1, so it impacts an application that implements it.
Do we have a defined policy for this?
It's not that much of a an issue, especially as we're still at the beginning of the 0.98, but it would worth mentioning it in the release notes imho...

> In case of Visibility labels, to support deletes we need to consider the visibility expression per version inorder to identify the matching visibility expression.
> Tracking the visibility tags along with the delete tracker would make things easier rather than handling during scans/compactions.
