Implement sorting that supports spilling in the $group stage for accurate percentiles

    • Type: Icon: Task Task
    • Resolution: Fixed
    • Priority: Icon: Major - P3 Major - P3

    • Fully Compatible

      We'll pass runs of sorted data from the GroupProcessor to the PercentileAccumulator to be sorted and used to calculate percentiles. If any single group exceeds the memory limit, we will uassert failure. This implementation will be extended by a secondary ticket to support spilling a second time in the accumulator.
