Description

ResultPartitions being released on consumption should no longer a hard-coded behavior, which is a prerequisite for making partitions consumable multiple times, without knowing ahead-of-time how often that might be. To retain the existing behavior a configurable flag should be introduced to force the consumption of all release partitions,which will likely be removed in the future.
