Pramod Immaneni commented on APEXCORE-408:
------------------------------------------
How about widening the scope to also trigger the changes when major events
happen in the execution such as operators getting killed or choosing to
shutdown? In general whenever a stram event gets created we could potentially
trigger the changes.

> Today it is possible to add operators to a running application from the
> CLI/client. It should be possible to do this from within the application
> also. This can be used to expand/remove a Sub-DAG on demand, triggered by
> application specific logic. It will enable use cases such as batch
> applications that perform multiple stages of processing where not all
> resources are required at the same time or the logic of subsequent steps
> depends on the execution of previous steps.
