Aug 1, 2025August 2025 saw a concerted push to enhance scheduling accuracy, observability, and release readiness across ytsaurus. Key work included scheduler and resource accounting improvements with precise CPU-to-vCPU rounding and fixed user ID slots, resulting in more predictable resource allocation and fewer scheduling anomalies. Observability was strengthened via job metrics, dashboards, and monitoring enhancements, including removing slot_index from metrics, a new Jobs Monitor dashboard generator, and the addition of total_cpu and total_memory sensors for the CRI environment. A major refactor of Solomon profiling and tag handling standardized metrics collection, enabling clearer attribution and scalable tagging. Release/version management updates align controller agent snapshots and overall releases to 25.4, ensuring compatibility with downstream systems. Disk health and error reporting were improved with enhanced diagnostics and consistent error formats, while test infrastructure was stabilized with migrations and environment improvements to boost reliability. The combined outcomes deliver tangible business value: more reliable scheduling, faster issue detection, safer releases, and improved development velocity.

Key features delivered: - GPU checks: reliability and configurability improvements, including environment-based cluster tagging via YT_INFINIBAND_CLUSTER, support for GPU check type via YT_GPU_CHECK_TYPE, and a configurable GPU test limit to enhance robustness (commits 35f256460d7a0c558f89e0063c2a598278866146; 30e56345d6bca0f1afa6fa50944ad90eec69e537; 5cafc08aea9df4d6855c776fd89d8da858c7abfe). - Admin access control improvements: granted write permissions to admins for the //sys/operations path to ensure proper administrative control (commit 6d55e22e516833838cd7e02338929aae401f7ce1). - Job ID generation cleanup: removed deprecated config option job_id_unequal_to_allocation_id to streamline job ID generation (commit 4f3de7f73aff6cd89f56fdcf27a0657210379e4e). - Table column renaming: enabled by default to simplify migrations and removed legacy compatibility tests related to the old default behavior (commit 08e3f68a9ee99856ea6e3629800900838f011ffb). - Release readiness: bumped project version from 25.2 to 25.3 as part of the release/development cycle (commit f9d5d00990fcad8334782addd403c605c1c39220). Major bugs fixed: - Improved proxy ban/unavailable logging to aid debugging and reduce troubleshooting time (commit 9832ec974c440a109d8830b0350f97d85bea796f). - Stabilized flaky network metric tests by relaxing waiting conditions to reduce false failures (commit dda16bd4da94f2f614a01ca0e9f45ed6e91bc284). Test infrastructure and packaging: - Cleaned up test packaging and serverless test setup (removals and __init__.py addition) to ensure proper packaging and test discovery (commits 127810f531a4720e0a6ffe99c730a98fd9d5aa27; d334316a5088ed2990f328de0c312fcda454a985). Overall impact and business value: - Increased reliability of GPU-related validation, tightened operational controls, streamlined configuration, and accelerated release readiness.
