Jul 1, 2025July 2025 monthly highlights for VKCOM/kphp: Delivered major coroutine runtime improvements and config data access refactor to boost performance, reliability, and scalability of asynchronous workflows. Implemented a script-based allocator for coroutine frames, a significantly refactored coroutine scheduler with a new stream API, fork API, and awaitables (when_all, when_any, event) to enable scalable production workloads. Introduced Config/Data Access API (k2::access), added a confdata component name constant, and updated the API header to expose the new access functionality, enabling more reliable confdata loading and downstream usage. No major customer-facing bug fixes were reported this period; focus was on stabilizing and accelerating core async infrastructure. Overall impact: higher throughput and lower latency for asynchronous tasks, with clearer, more maintainable APIs enabling downstream feature work.
