Jason Gauci commented on CRUNCH-320:
------------------------------------
Sorry for the delay, but I will try to test this out later this week.
If your patch fixes the test case that I posted, I'm sure it will fix our use
case as well.
> Materialize several PObject & PCollection objects in parallel (deferred
> materialization)

> Currently, Crunch blocks and materializes PCollections (through
> foo.materialize()) and PObjects (through foo.getValue()) on demand, but it
> would be a significant performance improvement if we could mark several of
> these objects as to be materialized, and then materialize all of them in
> parallel as part of a pipeline.run() call.
