Greg Glass contributed to the apple/foundationdb repository, focusing on codebase simplification, reliability, and maintainability over eight months. He removed deprecated features such as multi-tenancy, encryption-at-rest, and experimental modules, reducing maintenance overhead and streamlining upgrade paths. Using C++ and Python, Greg refactored core components, improved build and test stability, and enhanced observability with Prometheus-compatible metrics and detailed logging. He addressed security by replacing unsafe buffer operations and improved onboarding through Docker-based build documentation. His work included restoring legacy C bindings for Python compatibility and introducing robust error handling, demonstrating depth in backend development, system programming, and cross-language integration.

Feb 1, 2026February 2026 performance summary for apple/foundationdb: Focused on two main themes: (1) Codebase simplification by removing the encryption-at-rest feature (including related tests and configurations) to decrease maintenance complexity, and (2) reliability and observability improvements in the simulation framework to reduce false timeout signals and streamline debugging. Key outcomes: - Codebase simplification eliminates approximately 15,000 lines of code related to encryption at rest, simplifying critical paths, backups, and storage server code; progress toward removal includes test and config cleanups with ongoing verification. - Upgrade-test strategy adjusted by removing 7.1 upgrade tests to reduce cross-version fragility, while preserving 7.3/7.4 upgrade tests. - Simulation/logging enhancements introduced a unified TestProgress tag and improved progress visibility to differentiate between actual timeouts and ongoing work, expediting debugging and root-cause analysis. - Additional refactors and test hygiene improvements across the commits to improve compilation readiness and reduce incidental complexity, with compilation progress demonstrated though full end-to-end validation remains pending. Overall impact: reduces long-term maintenance burden and risk by removing deprecated encryption paths, improves reliability and debuggability of simulations, and lays groundwork for faster iteration cycles in future releases.

Jan 1, 2026Monthly summary for 2026-01 focusing on HealthMetricsApi reliability improvements in the apple/foundationdb repository. Delivered a flag-based data validation mechanism to ensure metrics are only processed after full reception, preventing false negatives, and introduced TraceEvents enhancements to improve debugging and observability. These changes reduce data-driven inaccuracies in workload reporting and provide faster triage signals for health metrics workloads.

Dec 1, 2025December 2025 monthly summary for apple/foundationdb highlighting feature removal and compatibility work. Focused on cleaning up legacy multi-tenant and metacluster features to reduce maintenance overhead, while preserving compatibility for legacy bindings where needed. Delivered a single, large codebase cleanup that eliminates tenant-related codepaths and references, and re-established essential C library bindings to support legacy Python bindings for 7.x ecosystems. These efforts simplify upgrade paths, reduce surface area for future bugs, and set the stage for future performance and reliability improvements.

Oct 1, 2025October 2025 (2025-10) — Apple FoundationDB: Decommissioned unowned experimental features to reduce maintenance burden and simplify the codebase. Key changes include removal of Blob Granule, ChangeFeed, and Storage Cache Server features, with a net removal of approximately 6,000 lines of code in core components (NativeAPI.actor.cpp and storageserver.actor.cpp). ChangeFeed removal was initiated and checkpointed; feature-status updated to has been deleted. Formatting improvements and documentation updates completed. Overnight CI surfaced test failures not related to these changes; no customer-facing bugs fixed this month.
