Xiang Li commented on HBASE-14881:
----------------------------------
Thanks for the comments, [~anoop.hbase]!
In my humble opinion, when it takes the whole row, such as in Put(byte[]) and
Put(byte[], long), I could use this.row=row to avoid the copying. But when it
takes a part of the provided rowArray as row, that is, when rowOffset and
rowLength are provided, I can not make this.row to point to the middle of
rowArray. Does Java provide a function to implement that? Please correct me if
I am wrong.
> Provide a Put API that uses the provided row without coping

> 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.
