-------------------------------------
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.
