Messenger can allow for some losses in degenerate infra cases, given a
given infra footprint. Also some ability to handle scale up faster as
demand increases, peak loads, etc. It therefore becomes a use case specific
optimization. Also hBase can run in Hadoop more easily, leveraging blobs
(HDFS), etc. So, depends on your use case.

I was under impression that with tunable consistency Cassandra can<br>
act as CP (in case it is needed), e.g by setting ALL on both reads<br>
and writes.<br>
Do you agree with this statement?<br>
<br>
PS Are there any other benefits of HBase you have found? I'd be glad<br>
to hear usecases list.<br>
