-----------------------------------
Summary: Remove Serializabiliy of ExecutionGraph
Key: FLINK-4312
URL: https://issues.apache.org/jira/browse/FLINK-4312
Project: Flink
Issue Type: Sub-task
Components: JobManager
Affects Versions: 1.1.0
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Priority: Minor
Fix For: 1.2.0
As a preparatory task for reworking the {{ExecutionGraph}} for finer grained
recovery, I would clean up the serializability:
- As long as a job is running, the ExecutionGraph cannot be serializable
- Once it is completed, the ExecutionGraph is sent to a local archive actor.
This does not require that the graph is serializable.
- In the future, archived execution data should be served from a static dump
of the execution data anyways, not from an archived graph. That allows us to
move the web monitor server to a separate trusted process (gateway /
dispatcher) that will never be in touch with user code.
