Subject Re: Hbase vs Cassandra

Hi Ajay,

You won't be able to get unbiased opinion here easily.  You'll need to try
and see how each works for your use case.  We use HBase for the SPM backend
and it has worked well for us - it's stable, handles billions and billions
of rows (I lost track of the actual number many moons ago) and fast, if you
get your key design right.  I'll answer your Q about monitoring:

I'd say both are equally well "monitorable".  SPM <http://sematext.com/spm>
can monitor both HBase and Cassandra equally well.  Because Cassandra is a
bit simpler (vs. HBase having multiple processes one needs to run), it's a
bit simpler to add monitoring to Cassandra, but the difference is small.

SPM is at http://sematext.com/spm if you want to have a look.  We expose
our own HBase clusters in the live demo, so you can see what metrics HBase
exposes.  We don't run Cassandra, so we can't show its graphs, but you can
see some charts, metrics, and filters for Cassandra at
http://blog.sematext.com/2014/06/02/announcement-cassandra-performance-monitoring-in-spm/

I hope this helps.

Otis
