Subject Re: Cassandra versus HBase performance study

Thanks for posting your results; it is an interesting read and we are
pleased to beat HBase in most workloads. :)

Since you originally benchmarked 0.4.2, you might be interested in the
speed gains in 0.5.  A couple graphs here:

0.6 (beta in a few weeks?) is looking even better. :)
