   > I created an issue https://github.com/apache/datafusion-comet/issues/4455 
so that we can have the discussion about whether Comet should support geo 
functions, and if so, what are the various options. Let's have this discussion 
before creating PRs.
   
   Hey,@andygrove 
   the current implementation on my branch uses WKB as the geometry 
representation and the pure Rust geo crate for all operations — there is no 
dependency on the GEOS C library. This addresses both the performance concern 
(WKB vs WKT) and the build dependency concern raised in the discussion.
