n8n's built-in memory is short-term by default and will be cleared after a service restart; for persistent cross-session memory, an external database such as Postgres or Redis must be connected.

UnverifiedSimple Memory temporarily stores context in server memory, and data will be lost after a restart; production-grade solutions typically persist data to external databases such as PostgreSQL or Redis.76% similarUnverifiedUAF漏洞的根源在于C语言的手动内存管理模型，free后的内存被标记为可重用但不会清除数据或使指针失效64% similarUnverifiedSecondary development of Redis caching involves multiple cross-cutting concerns such as read/write penetration, cache breakdown, and data consistency, and manual refactoring can easily miss update logic, causing inconsistencies between cached and database data.63% similarUnverifiedThe problem of memory drift almost never exists in traditional software, because what is written to the database is explicit field values, yet it occurs very easily in architectures that allow models to autonomously generate and update memories.61% similarUnverifiedProactively invalidating associated memories upon data changes yields a cleaner architecture, but requires tracking the source fingerprint of each memory entry, placing higher demands on system observability and data pipelines.61% similar
