 This will create a collection with all vectors immediately stored in memmap storage.
 This is the recommended way, in case your Qdrant instance operates with fast disks and you are working with large collections.

 The rule of thumb to set the memmap threshold parameter is simple:
 
 - if you have a balanced use scenario - set memmap threshold the same as `indexing_threshold` (default is 20000). In this case the optimizer will not make any extra runs and will optimize all thresholds at once.

 ## Payload storage
 
 Qdrant supports two types of payload storages: InMemory and OnDisk.
