I was trying to mix CQL2 and CQL3 to check whether a columnfamily with compound keys can be further indexed. Because using CQL3 secondary indexing on table with composite PRIMARY KEY is not possible. And surprisingly by mixing the CQL versions i was able to do so. But when i want to insert anything in the column family it gives me a rpc_timeout exception. I personally found it quite abnormal, so thought of posting this thing in forum.
