Can I transfer the whole collection to disk

[xtyDoge]

e.g index, vectors, payloads all to disk, I tried but it still cost 1GB memory for a collection . Why

Hi @xtyDoge, please refer to https://qdrant.tech/articles/memory-consumption/#how-to-measure-actual-memory-requirements

Qdrant will use all available memory for disk cache, you can limit it with external tools like docker.
