> Currently we do not catch unexpected exceptions in `onPartitionReassignment` in the controller. Generally this can lead to state inconsistencies and a failure to complete a reassignment. We should add exception handling and come up with a retry approach. For example, we could track failed reassignments in the controller context and retry them periodically.
