----------------------------------------

Thanks [~jkff] . I'll go through the links and propose an approach on this jira for implementing
ParDo chaining for Apex Runner.

> 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.
