Subject [jira] [Commented] (HBASE-16134) Introduce Cell extension for server side.
Date Tue, 20 Sep 2016 17:03:21 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16134?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15507134#comment-15507134
] 

Anoop Sam John commented on HBASE-16134:
----------------------------------------

#1 For replication we use this Codec. Also there is a config which can be used to specify
the Codec to be used.  So one can change to this Codec.
#2  It is not Reader which create Cells by HFileScanner - Ya we will have new scanner object
for the compaction read and that knows whether this is a compaction scan (Already it knows).
That is kind of ok
bq.Can MemSlab work here?
Sorry did not get. How MemSLAB can help?
bq.Just trying to have it so Tags are first-class. We just have to solve the issue that stops
Cells being put on the RPC. A flag is easy. Just trying to explore if any other possibility.
Understood.. Ya agree it is bit ugly.
Will it be better if we have 2 methods in ExtendedCell ie.  write(OS) and writeNoTags(OS)?
