Hi everyone, I have completed the first incremental stage of native geospatial support for StarRocks. The PR is now open and ready for technical review: github.com/StarRocks/starrocks/pull/78381 The PR introduces: • a native GEOMETRY SQL and storage type; • OGC WKT/WKB parsing and serialization; • POINT, LINESTRING, POLYGON, MULTIPOINT, MULTILINESTRING, MULTIPOLYGON, GEOMETRYCOLLECTION, and EMPTY geometries; • vectorized ST_GeomFromText, ST_AsText, ST_GeomFromWKB, and ST_AsBinary functions; • persistent storage integration, unit tests, and user documentation. The implementation has been built and validated locally, including persistence across BE restarts and WKT/WKB round-trip tests using a real Moscow districts dataset. Could someone please help route this PR to the appropriate FE, BE, storage, protobuf, and geospatial maintainers? I would especially appreciate feedback on the GEOMETRY representation, storage encoding, compatibility approach, and public SQL API. Thank you!
