1.DB-GPT支持的功能

2.配置StarRocks数据库

1. 支持多种数据库链接
2. 但是只支持一个库访问查询

3. ChatBI

1. 数据准确性不够精准，如果用于生产需要做相关优化
2. 查询可能会做大SQL查询，拖死web进程,无法响应

4. APP创建使用

dbgpt app install awel-flow-web-info-search
dbgpt app install awel-flow-example-chat
dbgpt app install awel-flow-simple-streaming-chat

安装可能因为网络问题报错，多执行几次就好了 。

5. 元数据库配置

 LOCAL_DB_TYPE=mysql
 LOCAL_DB_USER=
 LOCAL_DB_PASSWORD=
 LOCAL_DB_HOST=127.0.0.1
 LOCAL_DB_PORT=3306
 LOCAL_DB_NAME=dbgpt

6. API 调用探索

6.1 app

app chat api 模型替换 。

sk-xxx
https://dashscope.aliyuncs.com/compatible-mode/v1
llm model: qwen-long

6.2 datasources

1.list datasources api error 。

During handling of the above exception, another exception occurred:

6.3 Knowledge

1. 通过调用create_space接口失败但是创建了多个空间

2. 调用delete_space 删除不了空间

)
Reason: None

7. 问题总结

1. 可能会生成大查询SQL，导致查询卡死，响应非常慢
2. gbt任务会影响界面请求，gbt任务出问题会导致请求响应超时
3. 目前Chat data 、DB等响应还不够准确，可能跟模型有关？
4. 知识库创建的elsticsearch 卡片删除不掉
5. 无法强制杀死正在运行中的对话任务
