[GitHub] [incubator-sedona] jiayuasu commented on pull request #692: [SEDONA-170] Add ST_AddPoint and ST_RemovePoint to the Flink API

   This looks interesting. Does Flink already support ESRI geometry type before your PR? I checked their doc (https://nightlies.apache.org/flink/flink-docs-master/docs/dev/table/types/#data-types-in-the-table-api): Geometry is not listed as primitive type.
   
   In addition, some functions such as spatial aggregation might be able to be ported from Calcite to Flink. Some functions such as ST_Subdivide are actually implemented by Sedona committers for Spark. We just simply port them to Flink.
