    Description

      Another aggregate function we’ll need to look at is median().

      That should in theory map to the existing quantile kernel and the hopefully-coming-soon hash_quantile kernel with q = 0.5, but that will not work right now for several reasons (see https://issues.apache.org/jira/browse/ARROW-13309).

      However we also have a pair of
      approximate quantile kernels: tdigest and hash_tdigest that we could map median() to.
