February 2026 monthly summary for NVIDIA/spark-rapids-jni. Focused on stability and compatibility with cudf library changes. Implemented a compile fix by replacing cudf::device_span with cuda::std::span and explicitly constructing device_spans to maintain functionality, aligning with rapidsai/cudf#21283 (#4261). This prevents build-time blockers and preserves JNI bridge functionality for downstream Spark- RAPIDS features.

January 2026 (NVIDIA/spark-rapids-jni) focused on codebase hygiene, developer tooling stabilization, and build/compatibility maintenance to improve maintainability, developer productivity, and forward compatibility for the JNI bridge in Spark RAPIDS. Key refactors and fixes were implemented without changing runtime behavior, targeting long-term business value such as reduced maintenance costs, faster onboarding, and fewer build-time warnings.

In 2025-12, delivered Spark-compatible SHA-2 hashing with null preservation and fixed Murmur Hash compile compatibility with CUDF seed type changes, improving correctness, compatibility, and build reliability for NVIDIA/spark-rapids-jni. This enhances Spark semantics alignment for hashing and reduces maintenance risk by stabilizing builds and submodule sync. Technologies demonstrated include CUDA C++, cuDF integration, JNI bridging, and build-system resilience, enabling smoother analytics pipelines and faster onboarding.

June 2025 (2025-06) — rapidsai/cuvs: Focused on strengthening artifact publication workflow. Implemented centralized Maven publication artifacts by copying pom.xml to the target directory after builds, ensuring all Maven publication artifacts are available in a single, predictable location. This work reduces downstream setup time, improves reproducibility, and sets the stage for streamlined publishing in CI/CD pipelines.

Month: 2025-05 — NVIDIA/spark-rapids-jni: CI stabilization and reliability improvements focused on the KudoGpuSerializerTest. No new user-facing features delivered this month; efforts concentrated on unblocking CI and setting the stage for root-cause resolution.
