Kontinuation opened a new pull request, #12346: URL: https://github.com/apache/iceberg/pull/12346
This adds 2 primitive types to `iceberg-api` and `iceberg-core` for supporting geospatial data types, partially implementing the iceberg geo spec: https://github.com/apache/iceberg/pull/10981 The newly added primitive types are: * `geometry(C)`: geometries with linear/planar edge interpolation * `geography(C, A)`: geometries with non-linear edge interpolation, the algorithm for interpolating edges is parameterized by `A`. This patch also adds 2 expressions for filtering spatial values: * `ST_INTERSECT(geom1: geometry, geom2: geometry)` or `ST_INTERSECT(geog1: geography, geog2: geography)`: test if 2 spatial objects intersect with each other. * `ST_COVERS(geom1: geometry, geom2: geometry)` or `ST_COVERS(geog1: geography, geog2: geography)`: test if one spatial object completely covers the other spatial object. Currently we have implemented these 2 expressions for geometry values, the implementation for geography values is not fully implemented yet. We are looking into supporting geography with spherical edge interpolation algorithm using approaches similar to https://github.com/paleolimbot/s2geography. -- This is an automated message from the Apache Git Service.
