             Summary: Add utilities for heap-backed keyed state in time panes
                 Key: FLINK-2683
                 URL: https://issues.apache.org/jira/browse/FLINK-2683
             Project: Flink
          Issue Type: Sub-task
          Components: Streaming
    Affects Versions: 0.10
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 0.10


Time panes are commonly used for aligned time windows (tumbling and sliding). These utilities would represent the panes with per-pane keyed state.

The implementation must support:
  - Evicting panes efficiently
  - iterating over the union of all panes' state per key for all keys (computing the window function for all keys)
  - efficient append the state for a key in a random pane
