Subject [jira] Updated: (HBASE-748) Add an efficient way to batch update many rows
Date Sat, 11 Oct 2008 00:53:44 GMT

     [ https://issues.apache.org/jira/browse/HBASE-748?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HBASE-748:
------------------------

    Attachment: hbase-748-v4.patch

Problem was deserializing the BatchUpdate, we'd use the no-arg BatchUpdate constructor.  The
no-arg BatchUpdate waterfalls down to the constructor that takes all arguments.  It did this:

{code}
this.size = row.length;
{code}

If no-arg constructor, row was null.  The NPE wasn't making it out during deserialization.

This attached patch includes fix and some little cleanup.

> 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.
