Subject [jira] [Commented] (HBASE-17484) Add non cached version of OffheapKV for write path
Date Wed, 18 Jan 2017 16:05:26 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17484?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15828322#comment-15828322
] 

Ted Yu commented on HBASE-17484:
--------------------------------

Looks good overall.
{code}
26	 * This Cell is an implementation of {@link ByteBufferCell} where the data resides in off
heap
{code}
The above javadoc seems to be copied from OffheapKeyValue.

I think mentioning OffheapKeyValue is more appropriate.

> After running lot of different performance tests for various scenarios and with multi
threads we thought that is  better to have a version of OffheapKV in write path that does
not cache anything and its fixed_overhead is equal to that in KeyValue.
