> FlowFileRepository / WriteAhead Log should use a BufferedOutputStream when

>
> Currently, calls to MinimalLockingWirteAheadLog's checkpoint() method create
> a FileOutputStream, then wrap that in a DataOutputStream and start writing to
> the DataOutputStream, passing that along the SerDe as well. The
> FileOutputStream that it writes to should be wrapped in a
> BufferedOutputStream, as each call to checkpoint() is very taxing on the file
> system currently.
