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.
A JSON-serialized representation of an Offset that is used for saving offsets to the offset log.
Note: We assume that equivalent/equal offsets serialize to identical JSON strings.
