Subject Re: Interesting YCBS Benchmark
Date Fri, 11 Feb 2011 15:36:36 GMT
Whatever happened, something was way off the way they used HBase.
Adding machines adds latency whaaaaat?

Also this is not the YCSB like everyone wrote, the post was updated with this :

Update: A few users that had more luck reading the details on the
slides have pointed out that this is not the YCBS benchmark, but
rather a new one developed by the presenter. Another detail that’s
important is that data used was rather small and could easily fit in

It seems they released the code 2 days ago:
http://www.nosqlbenchmarking.com/ so I guess someone will have to look
at how they used HBase. Ryan found that the YCSB was adding a lot of
latency just the way they used the Result API (it's now fixed), maybe
we'll find the same here.

Finally, in research the most important step is validation of the
results. They wrote that in the HBase case they "checked the logs" and
"ran the balancer". Basically their numbers were not validated, the
most basic thing to do would have been to contact the devs of each
nosql database like the YCSB guys did.
