Subject [jira] Commented: (HBASE-1845) MultiGet, MultiDelete, and MultiPut - batched to the appropriate region servers
Date Tue, 08 Jun 2010 15:25:17 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1845?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12876698#action_12876698

Marc Limotte commented on HBASE-1845:
-------------------------------------

I think you're right that you could accomplish some of the same things with the Scan/Filter
semantics.  Multi has a couple of additional capabilities.

Scan is limited to one table.  Multi can do Gets from lots of different tables.  This applies
to families or columns, too.

Second, Multi lets you mix and match Get, Put and Delete.  It's not clear to me how often
that will happen, but it's there.
