------------------------------
[~tianchen92] Right, in some scenario, Resource are very precious and rare, we
can't allocate all slot for the streaming job at beginning, So the schedule
mode ScheduleMode.LAZY_FROM_SOURCES is in great need.
Embarrassing, I am working on this problem and recently is busy with other
things
> Make ScheduleMode configurable via user code or configuration file

> URL: https://issues.apache.org/jira/browse/FLINK-11619
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream
> Reporter: yuqi
> Assignee: yuqi
> Priority: Major
>
> Currently, Schedule mode for stream job is always
> see StreamingJobGraphGenerator#createJobGraph
> {code:java}
> // make sure that all vertices start immediately
> jobGraph.setScheduleMode(ScheduleMode.EAGER);
> {code}
> on this point, we can make ScheduleMode configurable to user so as to adapt
> different environment. Users can set this option via env.setScheduleMode() in
> code, or make it optional in configuration.
> Anyone's help and suggestions is welcomed.
