> Provide a way for a {{SourceTask}} implementation to record a new offset for a given partition without necessarily writing a source record to a topic.
> Consider a connector task that uses the same offset when producing an unknown number of {{SourceRecord}} objects (e.g., it is taking a snapshot of a database). Once the task completes those records, the connector wants to update the offsets (e.g., the snapshot is complete) but has no more records to be written to a topic. With this change, the task could simply supply an updated offset.
