     The property `eachBatchAutoResolve` is supported.
     Within the `eachBatch` callback, use of `uncommittedOffsets` is unsupported,

 * `commitOffsets`:
   - Does not yet support sending metadata for topic partitions being committed.
   - If called with no arguments, it commits all offsets passed to the user (or the stored offsets, if manually handling offset storage using `consumer.storeOffsets`).
