secondary index in HBase ?
Hi
is there any support of secondary index in Hbase ?
The Pigi mailing list pointed me to
http://svn.apache.org/repos/asf/hadoop/hbase/trunk/src/java/org/apache/hadoop/hbase/client/tableindexed/
does this package handle secondary index ?
I couldn't find it in the latest release, can I use the latest SVN snapshot
for leveraing this feature ? when is it going to be released ?
suppose I create a secondary index on one column in the main table. how can
leverage the index and iterate over the indexed columns ? how fast is it ?
