this question may have been asked many times, but could not find any suitable answer. Is there any ORM on Rails3 for Cassandra.
I have searched google and found following.
- fauna/cassandra – cassandra client for rails
- carbonfive/active_column – last updated 13-may-2011
- winebarrel/activerecord-cassandra-adapter – last updated 5 months ago
- scrum8/cassandrb – last updated 01-mar-2011
- NZKoz/cassandra_object – last updated 30-may-2010
- astrails/smallrecord – last updated 14-apr-2010
- azati/ActiveCassandra – last updated 03-jun-2010
Please help me out in deciding which one I should go with.
Thanks
First, you can put anything not updated in 2011 on the “don’t bother” list. 0.7 was released in January 2011 and has some API incompatiblities with earlier clients.
Of the ones left, fauna/cassandra is a lower-level client (I suspect most of the others use it as a starting point), which leaves a very short list left to evaluate. Based purely on commit activity I suspect active_column is your best bet.
For 0.8.1 (it won’t be ready in time to ship with 0.8.0) we’re working on a CQL driver that we hope will provide Rails compatibility out of the box. That will be in the Cassandra source tree under drivers/ when it’s ready.
