Hi, There is a new commit to YCSB:
http://github.com/brianfrankcooper/YCSB http://github.com/brianfrankcooper/YCSB/commit/6676f080d4c624eeb0ae56b548c8786742be3be3 This fixes performance problems in the HBase DB adapter. In my own tests I found that my short scans, which were configured to read 100-column rows, 1-300 in zipfian, went from 60ms to 35ms. Also there is column selection pushdown enabled, which will improve the speed of any tests that are doing single column gets on a wide row (eg: readallfields=false, fieldcount=X). This is all due to changing how YCSB uses the Result object. Check out the commit for some hints. I have a longer email and patch about this stuff coming really soon. -ryan
