Where is the index stored?

Where is the index stored ? In RAM, or on disk. What are the requirements for the machine if I am going to store 1 000 000 openAI vectors

Hi @IvankoPo - you can find resource recommendations here: Resource Planning | Weaviate - vector database

The indexes are mostly loaded into memory I believe, but can be persisted to disk. Some techniques like PQ (Vector Indexing | Weaviate - vector database) allow a mix of disk-stored and memory-loaded indexes for efficiency.
