Subject [jira] [Commented] (HBASE-19033) Allow CP users to change versions and TTL before opening StoreScanner
Date Thu, 26 Oct 2017 17:12:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-19033?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16220813#comment-16220813

Anoop Sam John commented on HBASE-19033:
----------------------------------------

ScanOptions  ->  I was thinking why to have this extra interface and this object having
ScanInfo. Why not pass ScanInf itself (cloned value). But then I see it is IA private.   ScanInfo
 is having some other states which also CP user might want to change? Like keepDeletedCells?
 I dont know. Just asking.  But that is having certain things which is not to be exposed to
CPs.  So I think ScanOptions interface way is ok.  After all it is an interface type being
passed so we can add what new wanted with out any BC break any time.  I think this patch is
coming good.

> See the discussion in HBASE-19001. Changing versions and TTL is safe for flush/compaction
so we can expose them.
