Robert Stupp commented on CASSANDRA-7396:
-----------------------------------------
bq. It's definitively worth having proper syntactic sugar here
agree
UDFs are not a requirement for this one - but may help to quickly add new
functionality with the option to optimize that later (using CASSANDRA-7085,
optimized slice queries etc)
bq. slicing capabilities map[key1..key2]
maybe also to check which keys are present for a slice (or at all) and return
these keys
and some "containsKey(key1..key2)" (return a boolean or an int with the count
of the existing keys)
> Allow selecting Map key, List index
