Subject [jira] [Commented] (HBASE-14881) Provide a Put API that uses the provided row without coping
Date Tue, 19 Jul 2016 15:08:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14881?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15384314#comment-15384314

Anoop Sam John commented on HBASE-14881:
----------------------------------------

Seems like other comments are not addressed.
bq.Why no checkRow() when copyRow is false?
bq.copyRow
This looks like exposing the internal impl. Can we call this as ***Immutable?  bufferIsImmutable?

> The current available Put API always makes a copy of the rowkey.
> Let's provide an API that accepts an immutable byte array as rowkey without making a
copy.
> There are cases where the caller of Put has created the immutable byte array (e.g from
a serializer) and will not change it for the Put duration. We can avoid making a copy again.
