Subject [jira] [Commented] (HBASE-14881) Provide a Put API that uses the provided row without coping
Date Wed, 13 Jul 2016 15:58:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14881?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15375253#comment-15375253

Xiang Li commented on HBASE-14881:
----------------------------------

[~jinghe], is the patch you are expecting to have?

I provide 2 new constructors with a boolean as one of the parameters to decide if it makes
the copy or not and do not change the existing constructors.
The 2 new constructors take the whole byte[] row inputted as the row key, and do not support
to specify offset and length.

> 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.
