>
> 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.
