Subject Re: how does cassandra compare with mongodb?
Date Thu, 13 May 2010 20:54:01 GMT
Mongo has a rich query API and a weak distribution/replication story.
Cassandra has a narrow (read: weak) query API and a strong
distribution/replication story.  If you want really shallow learning
curve, easy querying, etc, won't have that much data, and are handy
with the typical master/slave replication model, Mongo is a fine
choice.  If you want to have billions of rows and tens or hundreds of
terabytes of data spread over tens or hundreds of machines in multiple
datacenters, and can manage the additional effort of maintaining your
own indices, Cassandra is the better choice.

All my opinions, apply grain of salt...
