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