Hi Piyush! First I have to ask what version of HBase you are on? For the new HBase 0.20 we have made some major rewrites of the internal structure to get much greater read and scan speeds.
Depending a little if you store your updates as versions or using the qualifier as a timestamp we have two different ways to query, you might know this already. you can either set the number of versions that you which to get returned or use a filter. Regards Erik
