    @mattyb149 and @markap14 with the 1.6.0 release approaching, do you think 
we've allowed enough time for review and testing?  Is this good to go?  Thanks.

> 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.
