abstract class Offset extends AnyRef
An abstract representation of progress through a MicroBatchStream or
ContinuousStream.
During execution, offsets provided by the data source implementation will be logged and used as
restart checkpoints. Each source should provide an offset implementation which the source can use
to reconstruct a position in the stream up to which data has been seen/processed.

A JSON-serialized representation of an Offset that is used for saving offsets to the offset log.
