Slava commented on HBASE-1014:
------------------------------
Hi.
I think that time synchronization of the servers is much easier than
clients, and also clients could be located in different time zones. About
the server crash, you right but again, it's much easy to sync time of the
servers than clients.
About transactions, yes client runs transaction, but writing to the
transaction log is done on server and timestamp is set at the stage where BU
is written to the transaction log and not when it written to physically.
Best Regards.

> The commit(BatchUpdate) and commit(list<BatchUpdate>) should return timestamp
> that BatchUpdate was committed with (in the case of commit(list<BatchUpdate>
> should return array of timestamps).
> This should reduce number of round trips and improve performance in update
> operations.
