> In order to allow {{SourceCoordinators}}s from different {{Sources}} (for
> example two different Kafka sources, or Kafka and Kinesis) to align
> watermarks, they have to be able to exchange information/aggregate watermarks
> from those different Sources. To enable this, we need to provide some
> {{CoordinatorStore}} concept, that would be a thread safe singleton.
