Jean-Daniel Cryans commented on HBASE-748:
------------------------------------------

bq. No javadoc for HConnection.getRegionServerForManyRows

On that particular part I still need to do some work so I didn't freeze it.

bq. Do HTable.flushCommits and HTable$ClientScanner.initialize need to be 
public? Can't they just be protected?

We need to be able to flushCommits if auto-commit is off. Regards 
HTable$ClientScanner.initialize, well it's not this in my patch but from what I 
see TransactionalTable needs it so it cannot be protected nor private.

> 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.
