Where does mem0 save memory if not set vector database?

[hongbo-miao]

I saw mem0 supports vector database for memory storage: https://docs.mem0.ai/components/vectordbs/overview.

For example,

config = {
    "vector_store": {
        "provider": "qdrant",
        "config": {
            "collection_name": "test",
            "host": "localhost",
            "port": 6333,
        }
    }
}

I am wondering when not vector_store field, where does mem0 save memory if not set vector database? Is it just temporally saving in the server memory? Thanks!

config = {
    "llm": {
        "provider": "openai",
        "config": {
            "model": config.MEMORY_MODEL,
            "temperature": config.MEMORY_MODEL_TEMPERATURE,
            "max_tokens": config.MEMORY_MODEL_MAX_TOKENS,
            "api_key": config.OPENAI_API_KEY,
        },
    },
    "embedder": {
        "provider": "openai",
        "config": {
            "api_key": config.OPENAI_API_KEY,
        },
    },
}

Hey @hongbo-miao that's a great question, since qdrant is used default, mem0 stores locally at /tmp/qdrant by default if novector_store config is provided.

I see, thanks for the info!
