DataStoreService

Sets whether data store functions should automatically retry or not.

DataStoreService does not respect this property because automatic retry has been disabled due to technical reasons. Therefore, you must implement systems for retrying operations yourself. It is possible that automatic retry will be enabled again in the future.

This function creates a DataStore instance with the provided name and scope. Subsequent calls to this method with the same name/scope will return the same object.

Using the scope parameter will restrict operations to that scope by automatically prepending the scope to keys in all operations done on the data store. This function also accepts an optional DataStoreOptions instance which includes options for enabling AllScopes. See Data Stores for details on scope.

This function returns the default GlobalDataStore. If you want to access a specific named data store instead, you should use the GetDataStore() function.

返回

local DataStoreService = game:GetService("DataStoreService")

local GlobalDataStore = DataStoreService:GetGlobalDataStore()

print(GlobalDataStore.Name)

This method returns an OrderedDataStore, similar to the way GetDataStore() does with GlobalDataStores. Subsequent calls to this method with the same name/scope will return the same object.

This function returns the number of data store requests that the current place can make based on the given Enum.DataStoreRequestType. Any requests made that exceed this budget are subject to throttling. Monitoring and adjusting the frequency of data store requests using this function is recommended.

Returns a DataStoreListingPages object for enumerating through all of the experience's data stores. It accepts an optional prefix parameter to only locate data stores whose names start with the provided prefix.

Only data stores containing at least one object will be listed via this function.
