[jira] [Commented] (HBASE-10244) store mvcc in store files per KV, discard during compactions based on scanner timeout

    [ https://issues.apache.org/jira/browse/HBASE-10244?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13857007#comment-13857007 ] 

Sergey Shelukhin commented on HBASE-10244:
------------------------------------------

Hmm, the first part is already done (comment in KeyValue for mvcc field is wrong), so we only need to extend it

> Initially, we can store via KV tag. For perf reasons, it might make sense to make it a first-class member of KV, but that would require HFileV4
