Subject [jira] [Commented] (HBASE-11054) Create new hook in StoreScanner to help user creating his own delete tracker
Date Thu, 24 Apr 2014 05:05:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11054?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13979288#comment-13979288

ramkrishna.s.vasudevan commented on HBASE-11054:
------------------------------------------------

>>Should we step back and rethink this code? Can this all be expressed via filters?
You mean the DeleteTrackers itself? Or this patch you mean?
By the time we call filterKV() in filters the cells masked by deletes are removed already.

> 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.
