Jun 1, 2025

Summary for 2025-06: Delivered three major feature enhancements in ydb-platform/ydb focused on reliable data export, backup validation, and cluster operability. Implemented gRPC topic export by extending exportable kinds with KindTopic and introducing a feature-flag for KindView export, enabling safer staged rollout. Added an S3 backup stress testing framework to validate end-to-end export, load handling, and cleanup within the YDB stress suite, improving reliability and CI feedback. Enhanced cluster information collection and bridge mode support, including reporting node PileId, ignoring proxy groups, and adapting state storage to support bridge mode with multiple ring groups and dynamic ring selection, boosting scalability and observability in complex deployments. These changes collectively improve data export reliability, backup durability, and operational flexibility.
