-----------------------------------------------------------
Yes. Bundle processing is keyed after a GroupByKey to ensure that per-key state
is accessed only by the appropriate key. Writing a limited number of output
files requires bundles to be merged, either via the runner doing so or adding
an intervening transform to do so.
