PROFILE
Gleb Natapov
Gleb worked extensively on the scylladb/scylladb repository, driving the transition to a raft-based topology and refactoring core distributed systems components for reliability and maintainability. He engineered host-ID-centric messaging, topology, and replication paths, replacing legacy IP-based logic to improve cluster consistency and scalability. Using C++ and Python, Gleb implemented robust concurrency controls, asynchronous event handling, and schema management, while enhancing observability and error handling throughout the stack. His work included deep code cleanup, migration of APIs to IDL, and the introduction of feature flags for safer rollouts. These efforts resulted in a more resilient, upgrade-friendly, and operationally clear codebase.

Apr 1, 2026April 2026 focused on improving code readability and maintainability in scylladb/scylladb by aligning topology-state terminology with actual semantics. The internal function is_dead_state was renamed to is_left to reflect that a node has left the gossiper topology, with all references updated accordingly. This change reduces confusion around topology state checks and lays groundwork for safer future topology-related enhancements. Implemented as a targeted refactor with minimal surface area impact.

Jan 1, 2026January 2026 monthly summary: Delivered raft-based topology management by deprecating legacy topology and enforcing raft mode across the cluster; added boot-time checks, disabled force-gossip-topology-changes, and removed obsolete raft upgrade code. Improved topology coordinator resilience during node replacement by ensuring pending operations complete with failure for replaced nodes and by skipping requests for nodes in the 'left' state during topology loading. Removed the upgrade path to group0 to simplify upgrade trajectories and retired the gossiper-based recovery approach; completed targeted test cleanup by removing deprecated consistent_cluster_management usage. These changes enhance reliability, reduce upgrade risk, and improve fault tolerance in production clusters. Key commits include: topology: disable force-gossip-topology-changes option (08268eee3ff6baac64eec615a519f6c995ceeede); storage_service: refuse to join a cluster in legacy mode (ed52d1a292633e9adfe26e9692438270199f54cf); group0: remove upgrade to group0 code (4a9cf687ccb52f8e50922f4f52a1ffca9bbae4fa); topology coordinator: complete pending operation for a replaced node (bee5f63cb62a22930efb8f2520cd9e7d03559082); test: get rid of consistent_cluster_management usage in test (9daa109d2c64336da10c551f528e546914169bfe).
