@mcvsubbu @kishoreg I am thinking along the lines of what @mcvsubbu proposed earlier. Introduce a new state like "EVICTED" in the segment FSM. A segment can move from ONLINE -> EVICTED (this transition can take place when a segment's retention period expires). The invariant is that an evicted segment is always present in the deep store. While querying, the broker gets all of the segments to be queried, sees that some of them have been evicted, triggers a download to a sub-set of servers, and then proceeds with its regular business. The segments remain cached in these servers, and can be replaced with some eviction policy if need be. What are your thoughts on this? (I through it will be a good idea to vet this approach before I get on with the design). -- This is an automated message from the Apache Git Service.
