Thomas Weise commented on BEAM-831:
-----------------------------------
There are changes needed on top of the original PR, I will submit a new PR.
Also I see that one of the unit tests does not terminate as expected when the
chaining is enabled, that needs to be looked into also.

> Project: Beam
> Issue Type: Improvement
> Components: runner-apex
> Reporter: Thomas Weise
> Assignee: Chinmay Kolhatkar
> Fix For: First stable release
>
>
> Current state of Apex runner creates a plan that will place each operator in
> a separate container (which would be processes when running on a YARN
> cluster). Often the ParDo operators can be collocated in same thread or
> container. Use Apex affinity/stream locality attributes for more efficient
> execution plan.
