Feb 1, 2026February 2026 monthly summary for ava-labs/firewood: Focused on performance, memory efficiency, reliability, and secure CI/CD. Delivered memory-based cache eviction via MemLruCache with per-entry heap-size accounting, introduced node_cache_memory_limit, added cache utilization metrics, and reinforced configuration validation. Tuned freelist cache: default size increased to 1M entries, added cache.freelist.size metric, reducing disk churn and improving observed cache performance. Exposed optional node cache memory limit to open args (FFI) to streamline coreth integration. Fixed persist worker behavior to clear last_committed_revision promptly after persistence, enabling faster revision reaping. Strengthened CI/CD security by pinning dependency versions and adding Dependabot configuration. Technologies/skills demonstrated: Rust memory management, custom heap accounting with lru-mem, HeapSize trait implementations, FFI adjustments, unit/integration testing, observability via new metrics, and CI security practices. Business impact: improved memory efficiency and stability under load, decreased disk churn, faster test cycles, and safer automated dependency updates.

Aug 1, 2025August 2025 highlights for ava-labs/firewood: Delivered targeted features and stability improvements that enhance observability, safety, and performance in the storage and persistence path. Key achievements include a Gauge Metrics Enhancement with the new firewood_gauge macro to track unwritten nodes, DOT graph dumps with refactored writers for easier debugging, and a type-safe storage upgrade introducing the AreaIndex newtype with a consolidated primitives module. Major bug fixes addressed concurrency and data integrity: an Allocated state to resolve the IO-URING race between persisted and written nodes, plus tests and safeguards around read-from-proposal during commits and DB path consistency. A new advisory file lock prevents multiple processes from opening the same DB file, complemented by a Rust toolchain upgrade to 1.89 enabling File::lock. Additional cleanups include mut_root to root_mut renaming for consistency and a FuzzTree rename for clarity. Overall, these changes improve reliability, data safety, and developer productivity while laying groundwork for future performance improvements.
