We are having trouble with RealtimeToOfflineSegmentsTask, doing rollups fills up the heap and causes bad GC stalls disconnecting ZK and rendering the minion useless until a restart. Since the task is time based it's not possible to size the minion heap to account for traffic spikes without overshooting towards too small segments When is the off-heap rollup support planned to be implemented? (mentioned in https://github.com/apache/incubator-pinot/pull/6847)

@Jackie is working on that. How close are you to finishing the offheap roll-up Jackie?

PR almost ready, will try to merge it by this week
