Thanks Doug, 

Nice ability to define column types on the fly,
and interpret them from incoming CSV.
Yes and treat as structure of arrays.

AFAICT Frames keeps each set of records distinct;
and wants each set to be same type/same columns and types.
So there's no heterogeneous repository.

There's standard filtering features you'd get with Set or
List.
I'm not seeing any ability to match/join across different
datasets.
That is, you'd have to write your own code.
