As a user I would like to listen on a key and receive only a subset of values at a time.

Sorting needs to be determined.

Introduce LVTS: LVTS guarantees everything later than itself up to RVTS has been synced.

LVTS and RVTS starts out the same, then as more historical data is needed, we make an advance call asking for n number of items before LVTS. LVTS is moved to the lowest VTS of the items returned.

Client SDKs are in charge of keeping track of LVTS/RVTS, and passing along the request for historical items.

Due the scope of the implementation we have decided on, this will not be finished during this sprint
