index_store.json, docstore.json, graph_store.json
do when I persist the index into my file system? And also what is the purpose of them when I later using the persisted index to query? I don't see so much information contained in them. I'm using PostgreSQL VectorStoreIndex with S3 File System. Thanks in advance.storage_context = StorageContext.from_defaults( persist_dir=user_s3_folder, vector_store=vector_store, fs=s3 ) index = load_index_from_storage( storage_context )
persist_dir
and fs
param if I only use PGVectorStore, right?
