During March 2025, Nartal focused on stabilizing Spark 355 compatibility and build integrity for the NVIDIA/spark-rapids repository. Addressing a critical build error, Nartal updated TrampolineConnectShims.scala by introducing a new Spark version identifier, ensuring seamless integration with the latest Spark release. The work also included refining Slice expression support in operatorsScore.csv and supportedExprs.csv, maintaining accurate evaluation across Spark versions. Leveraging skills in build engineering and Spark, and working primarily with Scala and CSV, Nartal’s targeted bug fix improved build stability and upgrade readiness. The contribution demonstrated a focused, in-depth approach to maintaining downstream reliability in a complex codebase.
