Oct 1, 2025Monthly summary for 2025-10 (facebook/sapling): Key features delivered: - API surface simplification: Removed deprecated bookmarks endpoint and related handler/metrics; bookmarks2 now supersedes functionality, reducing API surface and maintenance cost. - Fsnode support and observability: Introduced Fsnode type for manifest logging, integrated fsnodes with the manifest store, enabled access logging for fsnodes via the Mononoke API, and expanded unit tests to cover fsnodes and restricted paths. Major bugs fixed: - Stability/Performance: Reinstated and configured garbage collection for history entries in commit_cloud to delete outdated entries, with a configurable limit to prevent performance degradation; prevents unbounded growth of xdb.commit_cloud. Overall impact and accomplishments: - Business value: Simplified API surface reduces onboarding friction and maintenance bills, while maintaining feature parity via bookmarks2. Improved data hygiene and observability with fsnode logging and tests. GC fixes improve system stability and long-term storage health. - Technical impact: Clean API boundaries, enhanced manifest integration, broader test coverage, and metrics-enabled logging that supports quicker diagnosis and reliability. Technologies/skills demonstrated: - API design and deprecation strategy, logging/metrics instrumentation, manifest store integration, test-driven development, and performance-focused data lifecycle management.

Feb 1, 2025February 2025 (2025-02) monthly summary for facebook/sapling. Focused on delivering core features with improved performance, reliability, and observability, aligned with business value goals. Key achievements delivered this month: - New commit tailer: processing pipeline and diagnostics (channel-based routing, manifest derivation/backwards matching, and ODS logging). Commits: fe9ce999e0e969c935421503f3965f6f4c159f6f; 5bcaab551ea89880ec6611b3a9d85e36775ce487; 452861a9a058c2bb6a95176023df870a211bb322; dcf5850512b8bf26c796aca660489c4da64d879a; efeb6c07f91fb12cda73cf71fdf08c7abe6fa736. - Modern Sync: performance and parallelism improvements (processing-time measurement, faster changeset reading, larger channels, parallel file/tree sync, batched trees, and avoiding opening the target repo). Commits: 25bad294313a194975d4c2b2295faced4efc4b79; 765930f1f4fcc379b4373ea48597f67ae6287466; 106441136fafc730b9aeb4eb74b6337abdd042d0; e06b2f65569156f74d432f9c7bd13d8706a92349; b9c13b771928e14d96b54b16244eeb93674a92ba; 71d9c3e17abed759cd9835f4d068199e7b456f26. - Cloud: support date-based heads hiding in cloud commit workflow. Commit: ba27ac532e7d2379b14ff54ae95c9aa554ad87dc. - Modern Sync: Batch uploads and logging enhancements (batch content uploads, extra logging for contents, and removal of duplicate log). Commits: 2f81c6e349de1c01fb676a867680ed29ae2a749f; 3bb54fc410b87bbf479c698f0f8d7cb3309670b0; e5a20a744fec39b04b2de50f4318736be358ab8a. - Mononoke: CAS client integration with new commit tailer and migration cleanup. Commits: 1743bb0ddb2c25e24c97529aa591c4f5fe22299e; 48c412f4306a1511c393d9a16162d1d040d7c74b. Major improvements and experiments this month: - CAS client ergonomics improvements and tooling improvements in the tailer workflow. - Observability: logging enhancements across critical paths and improvements to ODS instrumentation. Note: A regression fix was applied to revert a changeset-reading speedup in Modern Sync to preserve stability, and EdenAPI lightweight cleanup completed to reduce noisy logs.
