Subject [jira] [Commented] (HBASE-11871) Avoid usage of KeyValueUtil#ensureKeyValue
Date Mon, 29 Sep 2014 16:22:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11871?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14151862#comment-14151862

stack commented on HBASE-11871:
-------------------------------

bq. Over all in read and write paths we don't anymore use KeyValueUtil#ensureKeyValue() and
all in Cell also now. 

Wahooo!!!

Test would be a Cell whose implementation was other than that of KVs.... say something from
prefix key or something simple that just changes location of one of the fields -- e.g. inlined
tags with key.

> Now we try to use diff impls of Cells (other than KV) in server side for optimizations.
(HBASE-11870  is one like this) Having code  KeyValueUtil#ensureKeyValue can be dangerous
as it recreate the Cell and do buffer copy. This is an umbrella issue.  Will raise small sub
tasks in specific areas and tackle this.
