Subject [jira] [Commented] (HBASE-16769) Deprecate/remove PB references from MasterObserver and RegionServerObserver
Date Thu, 06 Oct 2016 07:15:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15551142#comment-15551142

Anoop Sam John commented on HBASE-16769:
----------------------------------------

Ya I am getting ur point..  If u see, the convertion of many other PB objects to our objects
is for CP hooks alone..  Just take case of puts.  We convert each Mutation from PB object
to our POJO.  Cells are in plain bytes form only (CellScanner and Codec)..  Later in code
in HRegion and all, we just need the Cells.. Details whatever we need extra from Mutation,
we can very well get from PB object..  But we convert all Mutation PB to our POJO as we have
many hooks in the write path. JFYI.. may be this is a point for long term consideration?
