>
> Key: FLINK-11298
> URL: https://issues.apache.org/jira/browse/FLINK-11298
> Project: Flink
> Issue Type: Improvement
> Components: JobManager
> Reporter: shuai.xu
> Assignee: shuai.xu
> Priority: Major
>
> Now flink only support two scheduling modes, that's scheduling all tasks
> Eager for streaming jobs and scheduling all task Lazy_from_source for batch
> jobs. This is not flexible enough for the various requirements of different
> job such as FLINK-10240. We proposal a new ConcurrentSchedulingGroup based
> scheduling strategy which first split a job into serval concurrent groups and
> then schedule it in the unit of concurrent groups. This strategy will support
> not only the existing EAGER and LAZY_FROM_SOURCE mode but also other
> situation such as the Build/Probe in FLINK-10240.
