Developed and delivered NEAREST BY top-K ranking join functionality for the apache/spark repository, enabling efficient nearest-neighbor joins for recommendation and similarity analytics. The work spanned Spark SQL, PySpark DataFrame API, and Spark Connect, introducing new SQL grammar, planner and analyzer checks, and an optimizer rewrite to support the feature end-to-end. Implemented the nearestByJoin method in PySpark with Spark Connect integration, ensuring remote client support and cross-language API parity in Python and Scala. Comprehensive test coverage was added across multiple suites, reducing manual data manipulation and accelerating insights for users working with large-scale data in Spark environments.

May 1, 2026May 2026 Monthly Summary — Key feature delivery and cross-surface API expansion for NEAREST BY top-K joins. Delivered end-to-end NEAREST BY top-K ranking join across Spark SQL, PySpark DataFrame API, and Spark Connect, including SQL grammar, planner/analyzer checks, and optimizer rewrite. Exposed DataFrame API nearestByJoin in PySpark with Spark Connect wiring to support the same capability from remote clients. Implemented robust test coverage: PlanParserSuite, RewriteNearestByJoinSuite, SQLQueryTestSuite, DataFrameNearestByJoinSuite, and Spark Connect tests. Business impact: enables efficient, scalable nearest-neighbor joins for recommendations and similarity analytics; reduces manual data manipulation and speeds up insights. Technologies/skills demonstrated: Spark SQL, Catalyst optimizer, SQL grammar extension, multi-language API design (Scala/Java, PySpark), Spark Connect integration, comprehensive testing. Closes SPARK-56395 and SPARK-56395-DF-CONNECT2.
