Robert Stupp commented on CASSANDRA-7396:
-----------------------------------------
I still have [a branch|https://github.com/snazy/cassandra/tree/7396-coll-slice]
regularly rebased on trunk. Not sure, if it still works but it definitely needs
some more functionality to read only those "cells" that are actually requested
- i.e. only read the collection slice and not the whole collection. The current
impl reads the whole collection and just returns the slice. However, we could
split this into a separate ticket.
> Allow selecting Map key, List index
