Subject [jira] [Commented] (HBASE-10288) make mvcc an (optional) part of KV serialization
Date Fri, 10 Jan 2014 18:34:51 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10288?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13868094#comment-13868094

Andrew Purtell commented on HBASE-10288:
----------------------------------------

bq.  It can be done using tags, but we may not want the overhead given that it will be in
many KVs, so it might require HFileFormat vN+1

Only a minor version increment should be necessary.

> This has been suggested in HBASE-10241. Mvcc can currently be serialized in HFile, but
the mechanism is... magical. We might want to make it a part of proper serialization of the
KV. It can be done using tags, but we may not want the overhead given that it will be in many
KVs, so it might require HFileFormat vN+1. Regardless, the external  mechanism would need
to be removed while also preserving backward compat.
