Month: 2026-03 — Focused on strengthening WebSocket metadata access controls for Apache Pulsar. Delivered WebSocket Read-Only Mode feature with a new configuration option to enable read-only operations on the metadata store, including a corresponding configuration field and startup/test coverage. Fixed a critical bug where the metadataStoreAllowReadOnlyOperations setting was ignored by the WebSocket server, ensuring the read-only mode behaves as intended. These changes improve security, stability, and operational governance for WebSocket interactions with metadata, and were validated with targeted tests.
