I am observing a few issues -
1) I changed the replicas for a table from 1 to 3. All the segments that are created after the change have 3 replicas, but the pre-existing segments continue to have only 1 replica.
2) When a server node goes down, its hosted segments are not created on another node to maintain 3 replicas for the segments.
3) When I add a new server, no redistribution of segments happen automatically.
What are the expectations from Pinot in the above cases?
