Claude Code's caching mechanism caches the session context on each request to speed up subsequent responses; the cache has a time-to-live (TTL) and becomes invalid if unused for a certain period.

UnverifiedReusing the KV cache of identical context prefixes across requests can reduce redundant computation in the prefill stage, thereby lowering time-to-first-token (TTFT).73% similarUnverified缓存失效策略包括基于TTL的定期过期、基于业务事件的主动失效、以及人工标记不可缓存类别72% similarUnverifiedThe persistent context mechanism explicitly maintains a continuously updatable state cache, which is similar to the KV Cache mechanism of large language models in that both trade space for time.70% similarUnverifiedCommon architectural patterns for addressing state drift include setting a state TTL with forced refresh upon expiration, introducing event-driven mechanisms where external systems actively push state changes, and executing a read-validate-write process before critical decisions.68% similarUnverifiedCache breakdown can be addressed with mutex locks or a never-expire plus background asynchronous update approach; cache avalanche can be mitigated by adding random jitter to expiration times; cache penetration can be defended against with Bloom filters or by caching null values.67% similar
