    Description

      Currently StateMachineUpdater applies all the transactions until the committed index. In cases where there is a huge difference between applied and committed index, all these transactions would be pending in the state machine and can take a lot of heap space. Such a scenario was seen in the Ozone cluster where a large amount of heap was taken by unapplied transactions leading to frequent GC pauses.
