Subject [jira] [Commented] (HBASE-8849) CellCodec should write and read the memstoreTS/mvccVersion
Date Wed, 03 Jul 2013 06:30:21 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8849?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13698670#comment-13698670

stack commented on HBASE-8849:

Just say not to Writables... even WritableUtils.

The vint done in WritableUtils is bad.  See Benoit on this: https://github.com/OpenTSDB/asynchbase/blob/master/src/HBaseRpc.java#L849

Just do a long for now I'd say [~ram_krish]  We can come back later and make a fancier encoding....
should probably do some prefix encoding in here anyways -- why not... Can d later.

exists or 0 otherwise.
