--------------------------------------
Summary: Introduce a CoordinatorStore
Key: FLINK-24439
URL: https://issues.apache.org/jira/browse/FLINK-24439
Project: Flink
Issue Type: Sub-task
Components: Connectors / Common
Reporter: Piotr Nowojski
Assignee: Piotr Nowojski
Fix For: 1.15.0
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.
