hagerf edited a comment on issue #26087: [SPARK-29427][SQL] Create KeyValueGroupedDataset from existing columns in DataFrame URL: https://github.com/apache/spark/pull/26087#issuecomment-553431063 @HyukjinKwon The first link is not about Pandas, but ok, I just did a quick google. So basically the only way to get this PR merged is if enough people request it? I thought I made some good and valid points and with real use cases. The vast majority of people just use regular joins so obviously this is not the common case, but I still think it makes sense, and is a minor addition. If this isn't merged or even planned to be merged I'll probably have to create some a package called `org.apache.spark.sql`, but it obviously is a hack to go around a flaw or missing feature in Spark. Reflection is bad practice, so that should be avoided. Anyway, thanks for looking at it.
