srowen commented on issue #26762: [SPARK-30131] add array_median function URL: https://github.com/apache/spark/pull/26762#issuecomment-562098756 Yes, those are pretty different use cases; `approx_median` would also not compute a median over a whole column, and indeed, would be prohibitive enough to compute that I think we assume it isn't desirable vs a pretty tight bound on the median. (IIRC there are helper aggregator classes you can use to do it anyway) The other `array_*` functions are typically there for Hive parity and otherwise would be something users just apply a UDF for. It's not crazy, just think opinion has turned against adding things that aren't in Hive or standard SQL from here.
