davidchaava opened a new pull request, #28788: URL: https://github.com/apache/flink/pull/28788
## What is the purpose of the change This pull request adds SQL constructor and accessor functions for the `GEOGRAPHY` logical type introduced in #28740. The functions provide conversion between `GEOGRAPHY` values and their WKT/WKB representations. This PR is intended to be merged after #28740. Jira: https://issues.apache.org/jira/browse/FLINK-39904 Discussion: https://lists.apache.org/thread/flbj8dfdfgs26klrxt7xch3r9785ky67 ## Brief change log - Added `ST_GEOGFROMTEXT` and `ST_GEOGFROMWKB` constructors for creating `GEOGRAPHY` values from WKT and WKB. - Added `ST_ASTEXT` and `ST_ASWKB` accessors for converting `GEOGRAPHY` values to WKT and WKB. - Added planner registrations and runtime implementations for the functions. - Added planner integration tests and runtime unit tests. ## Verifying this change This change added tests and can be verified as follows: - Added planner integration tests for WKT/WKB constructor and accessor functions. - Added runtime unit tests for valid values and invalid WKT/WKB input. ## Does this pull request potentially affect one of the following parts: - Dependencies: no - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: no - The serializers: no - The runtime per-record code paths: yes - Anything that affects deployment or recovery: no - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? yes - If yes, how is the feature documented? docs ## Follow-up changes The following parts are intentionally left out of this PR: - PyFlink exposure for GEOGRAPHY schemas and functions. - Format-specific support, including Parquet integration. - Additional geospatial predicates and measurement functions beyond WKT/WKB constructor and accessor support. -- This is an automated message from the Apache Git Service.
