Hi Mike,
First of all, thanks for the link. It looks like an interesting read. I checked
that Aerospike is currently at version 3.8.2.3, and in the article, they are
evaluating version 3.5.4. The main thing that impressed me was their claim that
they can beat Cassandra and HBase by 8x for
Have you considered whether you have a scan heavy or a random access heavy
workload? Have you considered whether you always access / update a whole
row vs only a partial row? Kudu is a column store so has some
awesome performance characteristics when you are doing a lot of scanning of

I am just curious. How will Kudu compare with Aerospike
(http://www.aerospike.com)? I went to a Spark Roadshow and found out about this
piece of software. It appears to fit our use case perfectly since we are an
