EMR AI Assistant (also known as EMR Agent) lets you query resource information, diagnose component issues, troubleshoot Operations and Maintenance (O&M) failures, and start operations — all through natural language conversation. It is available for E-MapReduce (EMR) Serverless StarRocks and EMR on ECS.
As of January 9, 2026, EMR AI Assistant supports EMR Serverless StarRocks in addition to EMR on ECS. The assistant is currently in public preview, and its capabilities are continuously being expanded.
Supported regions
China (Hangzhou), China (Shanghai), China (Qingdao), China (Beijing), China (Ulanqab), and China (Shenzhen).
Feature overview
EMR AI Assistant provides three feature modules. The table below shows what each module does, when to use it, and example prompts to get started.
| Module | What it does | Example prompts |
|---|---|---|
| AI chat | Answers questions about StarRocks product features, architectural principles, version differences, best practices, and cloud deployment solutions. Provides instant AI chat services to help you quickly get technical support, solutions, or links to documentation. | "What issues are fixed in the latest version of StarRocks?" / "What instances are under my account?" / "What is the purpose of the pipeline_exec_thread_pool_thread_num parameter?" |
| Anomaly diagnosis | Retrieves the health status of an instance and the running status of SQL statements. Performs AI-powered analysis for issues such as CPU spikes, memory leaks, full disks, query timeouts, bad tablets, and metadata lock conflicts, then provides repair steps. Also analyzes top SQL queries, SQL type aggregation, and daily/weekly execution trends. | "The CPU usage spiked around 10:00. What was the cause?" / "What are the top 10 slow SQL statements for the instance today? Are there any changes from yesterday?" |
| Optimization suggestions | For Serverless StarRocks instances, automatically scans query history and system metrics to identify hot spots and data skew in SQL execution plans, then generates optimization suggestions for indexes, partitions, and materialized views. Also analyzes instance load and provides parameter tuning suggestions. | "QueryID: 6cb2\*\*\*\*\*-\*\*\*\*-\*\*\*\*-\*\*\*\*-\*\*\*\*\*\*8716 is slow. How can I optimize it?" / "Disk usage has been consistently high for the past week. How can I resolve this?" |
