@PlanetCassandra

1. First part of composite key [inside the inner brackets] is called “Partition Key”, rest [no inside the inner brackets] are “Cluster Keys”.

2. Cassandra stores columns differently when composite keys are used. Partition key becomes row key. Remaining keys are concatenated with each column name (“:” as separator) to form column names (cluster keys). Column values remain unchanged.

3. Cluster keys (other than partition keys) are ordered, and you cannot allowed search on random columns, you have to specify the entire cluster key and can run a range query on the final portion of it.
