Store and query structured data without planning schemas upfront. Use when you need to remember information, track entities across conversations, build knowledge bases, ingest API data, store user preferences, create CRM systems, or maintain any persistent state. Automatically evolves data structure as you discover new fields. No migrations, no schema design - just store data and query it.

无需预先设计模式即可存储和查询结构化数据。适用于需要记忆信息、跨对话跟踪实体、构建知识库、接入API数据、存储用户偏好、创建客户关系管理系统或维护任何持久状态的场景。系统会自动根据你发现的新字段演化数据结构，无需迁移，无需模式设计，只需存储数据并查询即可。
