> As-is, in the case of power loss or Operating System crash, we could have an update that is lost, and then an update for the same FlowFile that is not lost, because the updates for a given FlowFile can span partitions. If an update were written to Partition 1 and then to Partition 2 and Partition 2 is flushed to disk by the Operating System and then the Operating System crashes or power is lost before Partition 1 is flushed to disk, we could lose the update to Partition 1.
