jiayuasu opened a new pull request, #2628: URL: https://github.com/apache/sedona/pull/2628
## What changes were proposed in this pull request? Implements #908: Adds two geohash neighbor functions across all platforms: - **ST_GeoHashNeighbors(geohash)**: Returns an array of 8 neighboring geohash cells (N, NE, E, SE, S, SW, W, NW) - **ST_GeoHashNeighbor(geohash, direction)**: Returns a single neighbor in the given direction (n, ne, e, se, s, sw, w, nw, case-insensitive) Algorithm ported from geohash-java (Apache 2.0 license). ### Changes - **GeoHashUtils.java** (new): Shared base32 constants and decode lookup, eliminating duplication across GeoHashDecoder, PointGeoHashEncoder, and GeoHashNeighbor - **GeoHashNeighbor.java** (new): Core neighbor computation using bit-interleaving approach - **GeoHashDecoder.java**, **PointGeoHashEncoder.java**: Refactored to use shared GeoHashUtils constants - **InferredExpression.scala**: Added Array[String] type support for Spark SQL - **Spark**: Registered in Catalog, Functions, st_functions - **Flink**: Registered in Catalog, Functions with @DataTypeHint - **Snowflake**: Registered in UDFs and UDFsV2 - **Python**: Added to st_functions.py - **Tests**: Common unit tests (9), Spark SQL tests, Flink tests, Snowflake tests - **Docs**: Spark, Flink, Snowflake API documentation ## How was this patch tested? - 9 common unit tests covering known values, all 8 neighbors, circular movement, case insensitivity, null/empty/invalid inputs - Spark SQL functional tests - Flink SQL functional tests - Snowflake tester tests (TestFunctions + TestFunctionsV2) - All modules compile successfully -- This is an automated message from the Apache Git Service.
