Thanks for all your feedback.
Dan, your third option looks good ( cost of memory/oql need to consider). But
this should solves popular redis use cases "Top k/ multiple leaderboards use
cases, where subset of users/entity involves".
In general, Redis brings beautiful user apis which is very handful to end user.
They don't need to think about distributed nature of stores.
Geode brings strong consistency, high availability(in few seconds secondary
copy is available), wan-replication, Async queue and many more enterprise
features.
Thus providing those apis on top of Geode should generate good value.
Thanks Again.Hitesh.

Deltas would help. If the regions are persistent, the whole new value does
get written to disk though.
I suppose a third option would be to store all collections in the same
region, but store each element of the collection as a separate entry. For
example for HSET rkey rfield rvalue would create an entry with a geode key
of (rkey, rfield) in a REDIS_MAPS region. We could index the based on rkey.
That might make operations on the entire collection more expensive though;
those operations would all require using OQL queries.
