获取工作空间的宿主列表(高性能优化版本 v2)
|
||||
|
||||
优化策略:
|
||||
1. 批量查询 end_users(一次查询而非循环)
|
||||
2. 并发查询所有用户的记忆数量(Neo4j)
|
||||
3. RAG 模式使用批量查询(一次 SQL)
|
||||
4. 只返回必要字段减少数据传输
|
||||
5. 添加短期缓存减少重复查询
|
||||
6. 并发执行配置查询和记忆数量查询
|
||||
|
||||
返回格式:
|
||||
{
|
||||
"end_user": {"id": "uuid", "other_name": "名称"},
|
||||
"memory_num": {"total": 数量},
|

|

返回工作空间下的宿主列表,支持分页查询和模糊搜索。
|
