HBase and Cassandra for Rails - BigRecord (bigrecord.org)

I'm one of the people working on this project, and would really appreciate any feedback! Especially from the HN community.

This looks good, but I have not tried installing and running it. Something similar I have spend some time playing with (no real projects with it yet, though):

gem install cassandra

cassandra_helper cassandra

This installs all of the Java libs required to run Cassandra and provides a nice Ruby client.
