During three months contributing to apache/incubator-gluten, Srnk focused on backend and build system improvements using C++, CMake, and Scala. Srnk reorganized Scala source files to align with best practices, enhancing maintainability and onboarding for new contributors. They improved observability by updating build flags and documentation to enable Jemalloc statistics printing, clarifying usage for developers. Srnk also centralized build configuration, integrating Velox CPU target flags and standardizing compiler warnings, which improved reliability and cross-module consistency. Addressing Spark compatibility, Srnk fixed a bug in dynamic partition pruning with Arrow Scan, restoring correct data processing and metric collection across Spark versions.
June 2025 monthly summary for apache/incubator-gluten. Focused on stabilizing Dynamic Partition Pruning (DPP) when using Arrow Scan. Delivered a targeted bug fix that restores correct data scanning and DPP behavior across Spark versions. Changes include metric collection for output rows in ArrowBatchScanExec and adjustments to ArrowBatchScanExecShim constructors for compatibility with different Spark versions. This work restores performance benefits and correctness of Arrow-backed DPP pipelines.
