Re: [I] [Sedona Core] Sedona doesn't clip raster to geometry extent in zonal statistics which can lead to inefficient queries [sedona]

   Hi @Imbruced , @jiayuasu , is anyone currently working on this?
   
   I'm a student contributing as part of a university course, and I'd like to take it if it's free. I saw the earlier go-ahead on this thread, so I wanted to check with Imbruced first rather than start something that overlaps.
   
   My reading is that getStatObjects walks the whole raster data array regardless of how small the roi is. Before writing anything, I'd want to confirm that cropping to the roi's envelope (intersected with the raster extent) is the approach you'd want, rather than routing it through the existing rasterization path.
   
   Happy to be redirected if this is spoken for!
