I finally was able to fix the restart issue. there were 2 massive bugs in
the CassandraCommitter:
- within open() the checkpoint entry was always overridden
- within close() the checkpoint entry was always deleted
in addition i have made the following changes:
- renamed GenericAtLeastOnceSink to GenericWriteAheadSink
- implemented a caching of the last committed checkpointID in the
CassandraCommitter
It's rather obvious that more tests are required.
