Jean-Daniel Cryans updated HBASE-748:
-------------------------------------
Attachment: hbase-748-v1.patch
Current status of this issue:
1- The way retries are handled client-side is ugly, cannot be reused for other
operations (so HBASE-880 wouldn't fit in).
2- There is duplicated code in the two HTable.commit and HRS.batchUpdate.
3- WRE and NSRE maybe should share a common super class.
4- If any exception is thrown server-side, like values are too long or columns
in the wrong format, the state of the whole transaction will be unknown to the
user.
But it does give a 2x boost when autoFlush is disabled.

> HBASE-747 introduced a simple way to batch update many rows. The goal of this
> issue is to have an enhanced version that will send many rows in a single RPC
> to each region server. To do this, the client code will have to figure which
> rows goes to which server, group them accordingly and then send them.
