Fields

external_storage_fallback_threshold: u64

The number of attempts the node will make to obtain a part from peers in the network before it fetches from external storage.

location: ExternalStorageLocation

Location of state parts.

num_concurrent_requests: u32

When fetching state parts from external storage, throttle fetch requests to this many concurrent requests.

num_concurrent_requests_during_catchup: u32

During catchup, the node will use a different number of concurrent requests to reduce the performance impact of state sync.
