FallbackTransactionKVStore

iota_storage::key_value_store

Struct FallbackTransactionKVStore 

Source 
pub struct FallbackTransactionKVStore { /* private fields */ }
Expand description

A TransactionKeyValueStoreTrait that falls back to a secondary store for any key for which the primary store returns None.

Will be used to check the local rocksdb store, before falling back to a remote scalable store.
