      Overview

      SERVER-138656 passes the group key slots as StreamingAggStage's cluster key slots. Build the cluster key slots correctly, per the contract added in SERVER-136257.

      Scope of Work

      • For each group key whose null and missing values may be interleaved in the input, use fillEmpty(k) as its cluster key slot; otherwise reuse the group key slot.
      • StreamingAggStage accepts at most 4 such keys (tassert 13625701); with more, fall back to hash $group.
