-This approach immediately places all incoming vectors on disk. You can configure a threshold so that small segments are kept in RAM, but large segments automatically move to memmap storage once they exceed that threshold. This is controlled by the `memmap_threshold` in the collection’s `optimizers_config`.

-If you want both dense and sparse vectors to be stored on disk, you need to enable `on_disk` for each type separately.

 For dense vectors, set `on_disk: true` inside `hnsw_config`.
