Subject [jira] Commented: (HBASE-748) Add an efficient way to batch update many rows
Date Fri, 26 Sep 2008 14:47:44 GMT

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

Should the RowLock be associated with the BatchUpdate rather than being supplied on commit?
That would allow us to remove one commit overload, and allow the client to associate the row
lock with multiple BatchUpdates for the same row.

This is in the scope of HBASE-880. Glad to see that I'm not the only one who saw that problem.

bq. +1 on moving checks into commit (or flushCommits).

That would be in commit since in flush it's too late IMO.

> 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.
