> In order to allow {{SourceCoordinator}}s from different {{Source}}s (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.
