Subject [jira] [Commented] (HBASE-11054) Create new hook in StoreScanner to help user creating his own delete tracker
Date Thu, 15 May 2014 01:04:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11054?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13998348#comment-13998348
] 

Andrew Purtell commented on HBASE-11054:
----------------------------------------

This is a new hook, we are not breaking anyone

bq.  I'd say policy should be no changes to method apis across minor versions

That would prevent any changes at all to coprocessor APIs in 0.98, we'd have to leave the
branch behind and move to trunk only.

> 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.
