> Emit checkpoint barriers earlier, before drawing the state snapshot

> Project: Flink
> Issue Type: Improvement
> Components: Streaming
> Affects Versions: 0.10
> Reporter: Stephan Ewen

> Fix For: 0.10

>
> State snapshot drawing and downstream barrier emitting occur in an atomic
> scope. Currently, the barriers are emitted after the state snapshot has been
> drawn.
> There is no reason why the barriers could not be emitted at the beginning of
> the atomic scope, and it would reduce the short stalls in the streaming
> pipeline when drawing the state snapshot of an operator checkpoint.
