Ilia Shakhov
Worked on the ydb-platform/ydb repository, delivering robust backup, recovery, and distributed systems features over nine months. Developed incremental and system tablet backup capabilities, integrated backup exclusion APIs, and enhanced maintenance workflows to improve operational resilience and data safety. Applied C++ and Python to implement actor-based concurrency, protocol buffer serialization, and fault-tolerant system design. Introduced changelogs, integrity validation with SHA-256 checksums, and feature flag management for safer rollouts. Addressed reliability through targeted bug fixes, race condition resolution, and improved documentation. The work emphasized maintainability, scalability, and clear operator workflows, resulting in more reliable backup, restore, and cluster management processes.

3 Commits • 2 Features
Mar 1, 2026March 2026 (ydb-platform/ydb) focused on documentation enhancements for backup and maintenance features and the introduction of SHA-256 based integrity checks for backup snapshots, with validation during backup/restore. The work improves rollout safety via feature flags, developer experience through clearer docs, and overall reliability of backup workflows. No major bugs fixed this month; primary value comes from improved documentation, defined activation paths, and data integrity safeguards.

Nov 1, 20252025-11 monthly summary focused on reliability, backup resilience, and recoverability for the ydb platform. Delivered system bootstrap and recovery enhancements to improve initial deployment reliability and recovery flows, and enhanced backup operations with selective tablet backups and batch-size tuning. Fixed a critical race-condition in the ydb tools restore Acquire() path, with an accompanying changelog and UX improvements (progress bar and cluster state options). Collectively these changes reduce bootstrap downtime, minimize backup/restore failures, and improve scalability for larger deployments.
