Subject [jira] [Created] (FLINK-4321) Initialize TaskExecutions directly with their starting state
Date Fri, 05 Aug 2016 16:44:21 GMT

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

             Summary: Initialize TaskExecutions directly with their starting state
                 Key: FLINK-4321
                 URL: https://issues.apache.org/jira/browse/FLINK-4321
             Project: Flink
          Issue Type: Sub-task
          Components: Distributed Coordination
    Affects Versions: 1.1.0
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 1.2.0


Currently, the CheckpointCoordinator injects state into the Executions of each vertex.

For more file grained recovery, not all executions need state at the same time, and different
executions may be scheduled at different points in time with different completed checkpoints.

Executions should hence be eagerly initialized with their checkpoint state handles.
