Hi Raja, Each table in Hbase will have data split into many Region Servers which would in turn be stored on different Datanodes in Hadoop. So if you have sequential insert's then all the data would go to a same Region server and it would get choked and you will end up not using the parallel power of Hbase. So its always better to have random inserts so that all the regions servers are simultaneously used.
I am also not expert in Hbase, so others may please correct me, if I am wrong.

Hi All, I'm new to HBASE. I understand that HBASE keeps its data sorted in the filesystem. So when we insert randomly, it takes time to sort. Where as when we insert sequentially, there is no need for HBASE to sort. But, i keep hearing from some of the users that, sequential inserts to HBASE is the worst case thing. Why is that ? -- View this message in context: http://old.nabble.com/Sequential-Inserts-In-HBASE.-tp30329923p30329923.html Sent from the HBase User mailing list archive at Nabble.com.
