Generally looks good. Please update code as fixups for easier re-review.

I don't get it. Previously the code was calling assertOperatorEqualsIgnoreOrder
Now it's more verbose, including manually calling toPages, dropping hash channels, converting to MaterializedResult.
i assume this is assertOperatorEqualsIgnoreOrder inlined, but what's the actual difference?
Is this really related to increasing the data set, as Produce more than single page in testHashAggregation commit message says?

This can take time.
Can we spill asynchronously?
spillToDisk();
return WorkProcessor.empty();
(then we need to updateMemory(); on next call..)

Added todo since this requires bigger operator refactor
