Overview
This version focuses on AIOps, end-to-end observability, and fine-grained permission control. Key updates include AI-assisted diagnostics and tuning, job status push notifications, expanded permissions, UX improvements, and OpenAPI enhancements.
Platform
New features
-
Flink AI assistant: An AI agent for job diagnostics and tuning. Initiate a diagnosis with a single click from the Flink AI assistant entry or the job O&M page. The system generates a diagnostic report with root cause analysis and optimization suggestions, and supports one-click tuning execution.
-
Message delivery: Push critical Flink job status changes to external systems across the entire job lifecycle to build real-time monitoring and alerting.
-
Fine-grained permissions: Grant users a dedicated permission to unlock SQL/YAML job drafts. A user can unlock a draft with either the "Develop SQL/YAML jobs (create, edit)" or the "Unlock SQL/YAML job drafts" permission, enabling stricter isolation between development and production environments.
Enhancements
-
Workspace cloning:
-
The required permission for workspace cloning is now Editor instead of Owner.
-
Automatically create a snapshot of a running streaming job before cloning to ensure data consistency.
-
Improved error messages for cross-architecture migrations and authorization exceptions.
-
-
Autotuning:
-
Autotuning now supports data ingestion jobs (CDC YAML).
-
Autotuning is now more tightly integrated with the job health score and dynamic updates, improving tuning accuracy and timeliness.
-
-
Member management: When you add a RAM role as a project member, the member list now displays the RAM role name directly.
-
Data lineage: The entry point is now in a submenu of the O&M center.
OpenAPI
OpenAPI optimizations for job drafts:
-
Create, update, query, deploy, and delete data ingestion job drafts (CDC YAML) through the OpenAPI. You can also list data ingestion job drafts.
-
Improved the renaming mechanism for job drafts.
