LangChain’s default in-memory chat history disappears when a process restarts and cannot reliably share context across application replicas. This guide shows how to use ScyllaDB as both a vector store and a durable conversation-history backend. With ScyllaDB Vector Search, LangChain’s Cassandra integrations, and RunnableWithMessageHistory, developers can retrieve relevant documents, preserve conversations by session ID, and build RAG chatbots that maintain context across restarts and horizontally scaled deployments.
