While I'm doing the work with Cassandra, I usually think the structure like this: KS - CF - Key - Super Column - Column But looks like I should change it to something like: KS - CF - Super Column - Key - Column Since CF-SuperColumn are combined within a single parameter: ColumnParent, and they are usually unique (single) in a query.
