> This will make the source interface more extensible in the future without breaking existing
sources (after the change). Right now, the context would have methods for element emission
and for retrieving the checkpoint lock for checkpointed sources. In the future this can be
extended to allow emission of elements with timestamp and for dealing with watermark emission.
