[jira] [Created] (FLINK-2313) Change Streaming Driver Execution
Model
Stephan Ewen created FLINK-2313:
-----------------------------------
Summary: Change Streaming Driver Execution Model
Key: FLINK-2313
URL: https://issues.apache.org/jira/browse/FLINK-2313
Project: Flink
Issue Type: Improvement
Components: Streaming
Reporter: Stephan Ewen
I would propose the following change to the Streaming Execution Environment:
When calling {{env.execute()}}, it does not block, but return an {{ExecutionContext}} object. This execution context has various methods, that allow you to control the execution:
- waitFor() -> Blocks until the job terminates, or the connection to the JobManager is lost.
- stop() -> initiates a clean stop
- cancel() -> cancels the program
- setParallelism() -> Later: adjusts the parallelism of the program
If this is voted as desirable, I would make a design how to do this...
