[FLINK-1425] [streaming] Add scheduling of all tasks at once
----
> Turn lazy operator execution off for streaming programs
> -------------------------------------------------------
>
> Key: FLINK-1425
> URL: https://issues.apache.org/jira/browse/FLINK-1425
> Project: Flink
> Issue Type: Task
> Components: Streaming
> Affects Versions: 0.9
> Reporter: Gyula Fora
> Assignee: Ufuk Celebi
>
> Streaming programs currently use the same lazy operator execution model as
> batch programs. This makes the functionality of some operators like time
> based windowing very awkward, since they start computing windows based on the
> start of the operator.
> Also, one should expect for streaming programs to run continuously so there
> is not much to gain from lazy execution.
