Subject Re: non-uniform region splits for index tables
Date Tue, 09 Mar 2010 23:57:15 GMT
A region split happens when a family grows bigger than 256MB, if you
have less than that in a whole table then it will be hosted in a
single region.

was that the load balancing of the data should be done automatically by HBase. Is any particular
reason that the balancing of the data doesn't happen automatically on secondary index tables
or do I miss some setting ?
