[jira] [Created] (FLINK-1808) Omit sending checkpoint barriers when
the execution graph is not running
Paris Carbone created FLINK-1808:
------------------------------------
Summary: Omit sending checkpoint barriers when the execution graph is not running
Key: FLINK-1808
URL: https://issues.apache.org/jira/browse/FLINK-1808
Project: Flink
Issue Type: Improvement
Components: Streaming
Reporter: Paris Carbone
Assignee: Paris Carbone
Currently the StreamCheckpointCoordinator sends barrier requests even when the executionGraph is in FAILING or RESTARTING status which results in unneeded potential communication and space overhead until the job restarts again. It should therefore simply omit sending barriers requests when the execution graph is not in a RUNNING state.
