Thanks for the response Oscar. Your understanding is correct at a high level.
I think the Parquet geo spec can be almost directly borrowed to Avro, here's the Parquet spec: https://github.com/apache/parquet-format/blob/3ce0760933b875bc8a11f5be0b883cd107b95b43/Geospatial.md I think this change would make Avro a great file format for a bunch of geospatial data analyses, and I appreciate your consideration of the proposal!
