             Summary: Materialize several PObject & PCollection objects in parallel (deferred
materialization)
                 Key: CRUNCH-320
                 URL: https://issues.apache.org/jira/browse/CRUNCH-320
             Project: Crunch
          Issue Type: Improvement
          Components: Core
            Reporter: Jason Gauci
            Assignee: Josh Wills


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.
