      Summary

      Provide the ability to calculate median and percentile of the numeric values in the $group and $setWindowFields stages of the aggregation pipeline.

      Motivation

      Percentile (and median, as its special case) are common statistical metrics. The absence of these accumulators makes MongoDB very unattractive for analytical use cases. Moreover, MongoDB Charts are struggling to provide essential data exploration functionality to their users without these metrics available from the server.
