Ah, this is one of those terribly bad misfortunes of naming. In the world of Cassandra there are /two/ separate things that are called "CQL" and have version numbers: * The Cassandra Query Language, those strings that look a bit like SQL with such statements as "INSERT" and "SELECT". The current version of that is 3.0.5, last time I looked. * The CQL wire format used to communicate these things. The current version of that is 2, last time I looked. The 'cql_version' parameter defines the /latter/ of these versions - that should be either 1 or 2. As far as I know there is no version 3 of the wire format. I expect the confusion here is that you're wanting to use CQL language version 3 - this is already supported. You'll want to ask for wire format 2 most likely, unless your server cluster is sufficiently old as to only support 1. It's confusing I know, but that's the terminology that Datastax came up with for Cassandra. :/ -- Paul Evans
