Subject Re: double and float in CQL
Date Thu, 11 Aug 2011 03:16:40 GMT
Neither actually, I installed the python cql driver with

pip install cql

and it came with it.  Looks like it's version 1.0.4

pip search cql
cql                       - Cassandra Query Language driver
  INSTALLED: 1.0.4 (latest)

Too old?
