I think this is expected. It's the first time I tested this in 0.96 or later. Still +1 here.
I'll do the same test in 0.96 next week. I'd expect it'll be similar to 0.98. With "pure" scan performance I mostly mean the internal "friction". I.e. everything in the blockcache and all KVs filtered at the server with a filter. But as you said, this is not a discussion thread. We can tackle performance improvements later in the cycle. -- Lars ________________________________ From: Andrew Purtell <[email protected]> To: "[email protected]" <[email protected]>; lars hofhansl <[email protected]> Cc: "[email protected]" <[email protected]> Sent: Saturday, January 25, 2014 3:13 PM Subject: Re: [VOTE] The 1st HBase 0.98.0 release candidate is available for download On Sat, Jan 25, 2014 at 2:35 PM, lars hofhansl <[email protected]> wrote: Raw scanning is about 30% slower than 0.94 in pure scan performance. My initial reaction to that is -0, but I don't think it holds up .0, just charts out work needed for .1. When developing on trunk we looked at the deltas between trunk and trunk+changes, not between releases. How different is this from 0.96 I wonder. -- Best regards, - Andy Problems worthy of attack prove their worth by hitting back. - Piet Hein (via Tom White)
