> 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.
