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

             Summary: Improve abstraction in AbstractAsyncIOCallable to better fit
                 Key: FLINK-7619
                 URL: https://issues.apache.org/jira/browse/FLINK-7619
             Project: Flink
          Issue Type: Improvement
          Components: State Backends, Checkpointing
            Reporter: Stefan Richter
            Assignee: Stefan Richter
            Priority: Minor


The abstraction of AbstractAsyncIOCallable does not fit to well with todays needs in checkpointing
backends. Originally, backends were assumed to only open one stream that is managed by the
abstraction. In fact, concrete implementations always extended that in practise. We can redo
this in a way that more resources can be managed by the abstraction.
