Subject Re: cql3 and cli composites columns

Once you have created the CF from cqlsh, switch over to cassandra-cli
and run "describe schema". It will show you the schema for all your
column families in syntax that can be passed back into cassandra-cli
to create them.

The cassandr-cli syntax that you are looking for is probably the "and
column_metadata =" section.
