-------------------------------------

             Summary: Introduce interface for CloseableRegistry to separate user from system-facing functionality
                 Key: FLINK-5325
                 URL: https://issues.apache.org/jira/browse/FLINK-5325
             Project: Flink
          Issue Type: Improvement
          Components: State Backends, Checkpointing
            Reporter: Stefan Richter
            Assignee: Stefan Richter


Currently, the API of {{CloseableRegistry}} exposes the {{close}} method to all client code. We should separate the API into a user-facing interface (allowing only for un/registration of {{Closeable}} and a system-facing part that also exposes the {{close}} method. This prevents users from accidentally calling {{close}}, thus closing resources that other callers registered.
