Thanks a lot for your reply ! In "https://sedona.apache.org/api/sql/Parameter/#explanation";, I found the following words. "Advanced users only!". I don't known what's that mean. Do I need to pay or donate to use this feature??

Non-spatial attributes in SpatialRDD are stored in the userData field of geometries. In a spatial join query result, the non-spatial attributes are stored in the userData of each geometry. You can access them using a Map or MapPair function. See: https://sedona.apache.org/tutorial/rdd/#read-other-attributes-in-an-spatialrdd 2. In SpatialSQL API, the index and spatial partitioning are automatically done on the fly. You can set some parameters here: https://sedona.apache.org/api/sql/Parameter/#explanation Thanks, Jia On Wed, Aug 31, 2022 at 7:06 AM ???? <[email protected]> wrote: Hello everybody, &nbsp; &nbsp; &nbsp; I found the&nbsp; RDD's result of the spatial&nbsp; join&nbsp; query did not&nbsp; have&nbsp; non-spatial&nbsp; attributes .&nbsp; So I use&nbsp; spatial&nbsp; SQL.&nbsp; But&nbsp;&nbsp; how to&nbsp; set partition and&nbsp; index when I use&nbsp; spatial&nbsp; SQL?
