Let me convert this JSON to some data model in Cassandra, where each one of the arrays is really a set without any replicates:

var data = , "data2":

Let me query such as this: data["data1"]["100"] to retrieve the sets. Anybody understand how you may model this in Cassandra? (The only real factor I emerged with was posts whose title would be a set value and the need for the column was a clear string, but that felt wrong.)

It isn't OK to serialize the sets as JSON as well as other string, which may get this to much simpler.

Also, I ought to observe that it's OK to separate data1 and data2 into separate ColumnFamilies, you no longer need that they are secrets within the same one.

This seems like employment for that SuperColumn.
