Nov 1, 2025November 2025 focused on strengthening distributed data workflows and interoperability in ytsaurus/ytsaurus. Delivered a Distributed Write Sessions API for the C++ SDK and client, with RPC support and accompanying documentation to accelerate adoption in distributed workloads. Extended table fragment writers to support YaMR and Proto data formats, enhancing data interoperability across pipelines. Implemented a protobuf validation simplification by removing timezone-related checks, reducing validation overhead and potential edge-case errors. These efforts improve scalability, maintainability, and time-to-value for distributed data workloads, with documentation to accelerate onboarding.

Oct 1, 2025October 2025 (ytsaurus/ytsaurus) focused on stability, security hardening, and enabling scalable distributed writes. Key work spanned race-condition mitigation, protobuf type correctness, distributed file write capabilities, and robust initialization sequencing for RPC components. Result: safer, more scalable file operations, improved data integrity, and reduced exposure risk in config handling. Highlights: - Implemented distributed file write protocol enabling cross-node coordination and updated client interfaces and proto definitions to support distributed writes. - Fixed a race condition in the file cache locking by switching to per-file LockFile with TEagerLockingFileCache and locking immediately after upload, eliminating TTL-related race windows. - Corrected protobuf integer mapping for datetime types, with DatetimeToProto tests to ensure correct signed/unsigned categorization for DATE, DATE32, DATETIME, DATETIME64, TIMESTAMP, TIMESTAMP64, preventing serialization issues. - Added RPC client initialization race protection to ensure RPC components initialize before TRpcRawClient, reducing chances of uninitialized states. - Security hardening: removed serialization/deserialization of the token field from configuration to minimize exposure risk. These changes collectively improve reliability, data integrity, scalability, and security, delivering measurable business value through safer distributed operations and cleaner security posture.
