May 2026: Focused reliability hardening for ydb-go-sdk with emphasis on multi-writer robustness and partition routing, delivering concrete improvements in data integrity and developer experience. Key features delivered include multi-writer robustness enhancements, Kafka hash partitioning reliability improvements, and practical documentation for multi-partition writers. These efforts reduce restart-related data risks, improve deterministic routing, and accelerate adoption through clear guidance and tests.

April 2026 (2026-04): Focused on delivering reliability and traceability enhancements in the ydb-go-sdk, with two core features driving improved routing, partitioning visibility, and write sequencing. The work emphasizes business value through safer partition routing, stronger multiwriter guarantees, and expanded test coverage to lock in reliability.

March 2026: Reliability and scalability enhancements across two core platforms delivered substantial business value. In ydb-platform/ydb, introduced a new Producer Interface with sequence-number based ordering and streamlined producer ID management, supported by tests validating payload integrity and ordering. Addressed a race condition in read session handling with a lock guard to ensure thread safety during concurrent operations. In ydb-platform/ydb-go-sdk, delivered a Multi-Writer Topic Writer with partitioning and idle-management to boost throughput and scalability, and fixed a resend issue when partitions split to improve delivery guarantees. Overall impact includes more reliable message ordering, higher throughput for topic-based messaging, and stronger resilience during partition changes, reducing operational risk and enabling more predictable performance. Demonstrated capabilities in concurrency control, API design for reliability, partition-aware architecture, and focused test coverage.

February 2026 — Delivered core SQS and partitioned workload improvements in YDB, enhancing reliability, throughput, and observability. Key features include optional CLI parameters and GetQueueUrl support for SQS interactions, keyed write sessions enabling per-key partitioning and related workload handling, and a robust restart mechanism for write sessions on unknown acks. Also introduced per-partition in-flight memory limits and new inflight metrics to improve stability and performance across topic workloads. These changes reduce configuration friction, enable finer-grained throughput, and provide better operational visibility for production workloads.

January 2026 monthly summary for ydb-platform/ydb: Delivered a robust bug fix in Partition Management addressing inactive partition handling, improving stability and error resilience for partition operations. This release adds a presence check, an explicit response field, and adjusted logic to prevent erroneous failures, contributing to higher reliability in production workloads.

December 2025: Delivered a set of reliability- and performance-focused enhancements to ydb-platform/ydb. Implemented AWS SQS workload with batch send/receive/delete and cross-platform build support, with improved FIFO validation and Windows build fixes. Stabilized MLP consumers by adding DLQ handling, fixing memory leaks, and refining navigation logic. Improved observability with metrics rework, moving initialization to the end of storage init and introducing status-based metric updates (and expanded timing buckets). Enhanced YDB CLI topic consumer UX with shared-consumer options (DLQ and max attempts) and simplified CLI exposure. Optimized Persqueue performance through improved caching and a new vacuum interval for message deadlines and storage efficiency. These changes collectively boost reliability, throughput, and operability in production.
