Re: Is it possible that HBase update performance is much better than read in YCSB test?

Try this HBase YCSB client instead: https://github.com/apurtell/ycsb/tree/new_hbase_client The HBase YCSB driver in the master repo holds on to one HTable instance per driver thread. We accumulate writes into a 12MB write buffer before flushing them en masse. This is why the behavior you are

Thank you Andrew, this is an excellent answer, I get it now. I will try your hbase client for a 'fair' test :-) Best Regards, Ming -Original Message- From: Andrew Purtell [mailto:apurt...@apache.org] Sent: Thursday, November 13, 2014 2:08 AM To: user@hbase.apache.org Cc: DeRoo, John
