LangChain: External Memory (Not Supported)

The following LangChain memory nodes are not supported on indie.money:

  • Memory Motorhead (memoryMotorhead) - Memory Postgres Chat (memoryPostgresChat) - Memory Redis Chat (memoryRedisChat) - Memory Xata (memoryXata) - Memory Zep (memoryZep) - Memory MongoDB Chat (memoryMongodbChat)

Why Not Supported

These memory backends require TCP connections to external databases (Postgres, Redis, MongoDB), which are not available in Cloudflare Workers.

What to Use Instead

Use the Memory Buffer Window node, which is supported and stores recent conversation history in Cloudflare KV.

Limitation: 1-hour TTL. For longer-lived memory, use an HTTP-based key-value store (e.g., Upstash Redis REST API via HTTP Request node).
