一、 智能对话

通过自然语言快速获取 StarRocks 的产品特性、架构原理、版本差异、最佳实践与云上部署方案：

示例：“StarRocks 的最新版本修复了哪些问题？”
示例：“账户下有哪些实例？”
示例：“pipeline\_exec\_thread\_pool\_thread\_num 参数的作用是什么？”

二、 异常诊断

支持通过自然语言查询实例健康状态与 SQL 运行情况，AI 自动分析 CPU 飙升、内存泄漏、磁盘写满、查询超时、tablet 坏块、元数据锁冲突等异常，并提供修复建议；同时可洞察 Top SQL、SQL 类型分布及日/周环比趋势，并对单条 SQL 进行深度诊断：

示例：“10 点左右 CPU 飙升，是什么原因造成的？”
示例：“今日 Top10 慢 SQL 有哪些？和昨天相比有变化吗？”

三、 优化建议

智能解析慢查询日志，展示 SQL 执行计划中的热点及数据倾斜，并生成索引、分区和物化视图的优化建议；同时智能解析实例的当前运行状态和负载，提供参数调优建议：

示例：“QueryID: 6cb2*****---****-******8716 查询较慢，应如何优化？”
示例：“最近一周磁盘使用率持续高水位，该如何解决？”

从 ECS 到 Serverless，EMR AI 助手持续增强

EMR AI助手的演进路径始终围绕用户真实痛点展开。在 EMR on ECS 场景中，它已验证了在复杂 Hadoop 生态下的咨询、诊断与操作唤起能力；如今，面对 Serverless StarRocks 这一全新产品形态，AI 助手并未简单复用原有逻辑，基于其全托管的免运维、引擎增强等特性，优化了诊断模型与优化策略，支持任务级诊断和优化建议。

EMR AI助手的使命，是让数据工程师都能专注于业务创新，运维同学能够快速全面的定位风险和调优。未来，我们将逐步覆盖更多 EMR 子产品与使用场景，持续引入自动化操作、成本优化、安全合规等新能力，打造真正“懂你所需、行你所想”的智能运维伙伴。
