             Summary: Introduce state handle replication mode for CheckpointCoordinator
                 Key: FLINK-5265
                 URL: https://issues.apache.org/jira/browse/FLINK-5265
             Project: Flink
          Issue Type: New Feature
          Components: State Backends, Checkpointing
    Affects Versions: 1.2.0
            Reporter: Stefan Richter


Currently, the {{CheckpointCoordinator}} only supports repartitioning of {{OperatorStateHandle}}s based on a split-and-distribute strategy. For future state types, such as broadcast or union state, we need a different repartitioning method that allows for replicating state handles to all subtasks.

This is the first step on the way to implementing broadcast and union states.
