Stateless Architecture
A distributed system design paradigm in which the server retains no session state between client requests; each request carries all necessary context independently. This property facilitates horizontal scaling and load balancing and is a fundamental characteristic of the REST architectural style and the HTTP protocol.

Timeline (last 90 days)
Stateless architecture means that servers do not retain client session information between requests; each request carries a complete self-describing context, allowing MCP Servers to be load-balanced and horizontally scaled just like ordinary HTTP APIs.
The cost of statelessness is that each request's payload may become larger, as context previously stored in sessions must be explicitly transmitted by the client with every request or managed through other persistence means.
Stateless does not mean memoryless; it simply moves the storage of state from the server to the client or an external persistence layer.
Common stateless practices include encoding session information into JWTs to be passed with each request, storing shared context in a database or vector store, and injecting tracking metadata into request headers via an API gateway.
Because stateless architecture does not share state between service nodes, it can handle growing load by adding instances and has strong horizontal scalability.
无状态服务天然适合容器化与Serverless架构，可随时重启、迁移而不丢失运行时数据
「无状态」指数据库服务本身不在服务端维护会话状态或连接上下文，每次读写请求都是自包含的
