Subject [jira] Commented: (HBASE-748) Add an efficient way to batch update many rows
Date Wed, 24 Sep 2008 21:29:46 GMT

    [ https://issues.apache.org/jira/browse/HBASE-748?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12634305#action_12634305

Jim Kellerman commented on HBASE-748:
-------------------------------------

Review of hbase-748-v1.patch

Shouldn't HRS.batchUpdate(final byte[] regionName, BatchUpdate[] b) return "i" if it falls
out of the try/catch block?
Currently it returns -1 which indicates (as I understand it) that the request was unsuccessful.

I do not understand how these changes implement retries since getRegionServerForManyRows does
not implement them nor does it call getRegionServerWithRetries which does.

> 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.
