Dec 1, 2025December 2025: Delivered a critical reliability improvement to the Kafka Proxy in ydb-platform/ydb by correcting the public hostname usage for Kafka communications and simplifying response handling in the TKafkaFindCoordinatorActor. This fix reduces misrouted traffic, enhances stability of broker-client interactions, and contributes to higher uptime in production. The change was implemented via commit 8e610d41879e6647fd363d899889a1df89d23f03, co-authored by Irina Skvortsova, and includes targeted refactoring to the hostname resolution and response flow.

Nov 1, 2025Monthly summary for 2025-11 focusing on features and reliability improvements in the ydb platform. Key features delivered and bug fixes improved messaging throughput, reliability, and UI capabilities, resulting in tangible business value such as reduced message processing latency and more flexible topic partitioning. Delivered items: - Wait Functionality Improvements Across Topic Reader and CLI: ensure messages are read to completion when wait is disabled, with refined reading status management and timeout handling across components. - Topic Put-Record Handler for UI main: new UI handler enabling sending messages with metadata to a specified partition within a topic. - Safe Iteration and Performance Enhancement in CleanWriters: refactors iteration logic to improve performance and prevent potential iterator invalidation during element erasure.
