      Currently a lot of stages can spill to disk, but in explain output they will report different sub-set of spilling statistics under different names:

      DocumentSourceGroup will report spilled bytes as numBytesSpilledEstimate

      DocumentSourceGraphLookup will report it as spilledBytes.

      DocumentSourceSort won't even report this metric

      In SERVER-99564 we will ensure that all spilling stages track internally all relevant metrics consistently.

      In this ticket we should make the change to explain output to be consistent as well.
