DataStoreService

Inherits from: Instance → Object

DataStoreService exposes methods for getting GlobalDataStore and OrderedDataStore objects. Data stores can only be accessed by game servers, so you can only use DataStoreService within a Script or a ModuleScript that is used by a Script.

See Data stores for an in-depth guide on data structure, management, error handling, limits, and more.

DataStoreService:GetDataStore

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 Versioning, listing, and caching for details on scope.

Parameters

NameTypeDefaultDescription
namestringName of the data store.
scopestringglobal(Optional) A string specifying the scope.
optionsInstancenil(Optional) A DataStoreOptions instance to enable experimental features and v2 API features.

Returns

TypeDescription
DataStoreA DataStore instance with provided name and optional scope.
FieldValue
securityNone
thread safetyUnsafe
capabilities["DataStore"]

DataStoreService:GetGlobalDataStore

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

Note that the DataStore returned by this function always uses the scope u. See Data stores for details on scope.

Returns

TypeDescription
DataStoreThe default GlobalDataStore instance.
FieldValue
securityNone
thread safetyUnsafe
capabilities["DataStore"]

Code samples: View on Creator Hub (get-a-globaldatastore-instance).

DataStoreService:GetOrderedDataStore

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.

Parameters

NameTypeDefaultDescription
namestringName of the ordered data store.
scopestringglobal(Optional) A string specifying the scope. Default is "global".

Returns

TypeDescription
OrderedDataStoreAn OrderedDataStore instance with the provided name and scope.
FieldValue
securityNone
thread safetyUnsafe
capabilities["DataStore"]

Code samples: View on Creator Hub (OrderedDataStore-Basics).

DataStoreService:GetRequestBudgetForRequestType

This function returns the number of data store requests that the current place can make based on the given 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.

Parameters

NameTypeDefaultDescription
requestTypeDataStoreRequestTypeThe DataStoreRequestType to check the budget for.

Returns

TypeDescription
intThe number of data store requests that can currently be made for the specified request type.
FieldValue
securityNone
thread safetyUnsafe
capabilities["DataStore"]

DataStoreService:ListDataStoresAsync

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.

Parameters

NameTypeDefaultDescription
prefixstring(Optional) Prefix to enumerate data stores that start with the given prefix.
pageSizeint0(Optional) Number of items to be returned in each page. If no value is given, the engine sends a default value of 0 to the data store web service, which in turn defaults to 32 items per page.
cursorstring(Optional) Cursor to continue iteration.

Returns

TypeDescription
DataStoreListingPagesDataStoreListingPages instance containing DataStoreInfo instances that provide details such as name, creation time, and time last updated.
FieldValue
tags["Yields"]
securityNone
thread safetyUnsafe
capabilities["DataStore"]

DataStoreService:SetRateLimitForRequestType

Sets the per-server rate limit (requests per minute) for a given Data Store request type. The configured limit overrides the default rate limit for that request type on the current server. The rate limit is calculated as rateLimit = baseLimit + (perPlayerLimit * numPlayers), where numPlayers is the current number of active players on the server. DataStoreRequestType.OnUpdate and DataStoreRequestType.UpdateAsync cannot be configured with this function. Calling this API with those request types will result in an error.

You should call this API once per request type during server initialization. We don't recommend calling this API during active experience logic. If called multiple times, the new limit definitions will immediately overwrite the previous ones.

The baseLimit and perPlayerLimit have different constraints depending on the request type. See the table below for more information.
