metasim commented on issue #16478: [SPARK-7768][SQL] Revise user defined types (UDT)
URL: https://github.com/apache/spark/pull/16478#issuecomment-593110103
 
 
   The [RasterFrames](https://rasterframes.io/) project has had a [UDT](https://github.com/locationtech/rasterframes/blob/develop/core/src/main/scala/org/apache/spark/sql/rf/TileUDT.scala) at its core for around 3 years. Aside from having to be declared under the `org.apache.spark.sql` package as a hack around `UserDefinedType` being package private, it has worked quite well. Is there some context or forum where sharing our experience might help pave the way for this to become an official API?
