Subject [jira] [Commented] (HBASE-11777) Find a way to use KV.setSequenceId() on Cells on the server-side read path
Date Thu, 21 Aug 2014 23:34:11 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11777?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14106149#comment-14106149
] 

stack commented on HBASE-11777:
-------------------------------

What would it take to make a Cell implementation with a mutable sequenceid Interface?  If
bulk loaded file and mutable sequenceid interface, rather than create new instance, just call
setSequenceId?

Otherwise, if new Cell for bulk loaded files only, it wouldn't be bad... but then was thinking
of a few scenarios where cluster is only bulk-loaded files.... of which we have a good few....
and some largish.

> Over in HBASE-11591 there was a need to set the sequenceId of the HFile to the bulk loaded
KVs.  Since we are trying to use the concept of Cells in the read path if we need to use setSequenceId(),
then the Cell has to be converted to KV and only KeyValue impl has the accessor setSequenceId().
> [~anoop.hbase] suggested if we can use a Server side impl of Cell and have these accessors
in them.
> This JIRA aims to solve this and see the related code changes that needs to be carried
out for this.
