[MapServer-dev] Using OGR geoparquet data in mapserver - no spatial filtering

[Michael Smith]

All,

Anyone know a current way to get mapserver to add spatial filtering on OGR geoparquet layers. Have been unable to get the actual sql query being used with CPL_DEBUG inside mapserver with CONFIG "CPL_DEBUG" "ON" but from the performance, it appears no spatial filtering is being done. I suspect code changes to mapogr would be needed to do this but wondering if anyone else has looked into this.

Also, I tried using ADBC connection to parquet, and while it worked (technically) it really used an excessive amount of CPU and memory over using the geoparquet driver. 

Mike
