# GS2-Datastore SDK API Reference

Specification of models and API references for GS2-Datastore SDK for various programming languages



## Models

### Namespace

Namespace

A Namespace allows multiple independent instances of the same service within a single project by separating data spaces and usage contexts.
Each GS2 service is managed on a per-namespace basis. Even when using the same service, if the Namespace differs, the data is treated as a completely independent data space.

Therefore, you must create a Namespace before you can start using each service.



|  | Type | Condition | Required | Default | Value Limits | Description |
| --- | --- | --- | --- | --- | --- | --- |
| namespaceId | string |  | * |  |  ~ 1024 chars | Namespace GRN<br>* Set automatically by the server |
| name | string |  | ✓ |  |  ~ 128 chars | Namespace name<br>Unique Namespace name. Specified using alphanumeric characters, hyphens (-), underscores (_), and periods (.). |
| description | string |  |  |  |  ~ 1024 chars | Description |
| transactionSetting | [TransactionSetting](#transactionsetting) |  |  |  |  | Transaction Setting<br>Configuration for controlling how distributed transactions are executed when processing datastore operations. Supports auto-run, atomic commit, and async processing options. |
| doneUploadScript | [ScriptSetting](#scriptsetting) |  |  |  |  | Script setting to be executed when upload completion (doneUpload event)<br>Script Trigger Reference - [`doneUpload`](../script/#doneupload) |
| logSetting | [LogSetting](#logsetting) |  |  |  |  | Log Output Setting<br>Configuration for outputting log data of datastore operations to GS2-Log. By specifying a GS2-Log Namespace, API request and response logs for data object uploads, downloads, and access control changes can be collected. |
| createdAt | long |  | * | Current time |  | Creation Timestamp<br>Unix time, milliseconds<br>* Set automatically by the server |
| updatedAt | long |  | * | Current time |  | Last Updated Timestamp<br>Unix time, milliseconds<br>* Set automatically by the server |
| revision | long |  |  | 0 | 0 ~ 9223372036854775805 | Revision |

### TransactionSetting

Transaction Setting

Transaction Setting controls execution methods, consistency, asynchronous processing, and conflict avoidance mechanisms of transactions.
Combining features like AutoRun, AtomicCommit, asynchronous execution using GS2-Distributor, batch application of script results, and asynchronous processing of Acquire Actions via GS2-JobQueue enables robust transaction management tailored to game logic.



|  | Type | Condition | Required | Default | Value Limits | Description |
| --- | --- | --- | --- | --- | --- | --- |
| enableAutoRun | bool |  |  | false |  | Whether to automatically execute issued transactions on the server side |
| enableAtomicCommit | bool | {enableAutoRun} == true |  | false |  | Whether to commit transactions atomically<br>* Enabled only if enableAutoRun is true |
| transactionUseDistributor | bool | {enableAtomicCommit} == true |  | false |  | Whether to execute transactions asynchronously<br>* Enabled only if enableAtomicCommit is true |
| commitScriptResultInUseDistributor | bool | {transactionUseDistributor} == true |  | false |  | Whether to execute the commit processing of the script result asynchronously<br>* Enabled only if transactionUseDistributor is true |
| acquireActionUseJobQueue | bool | {enableAtomicCommit} == true |  | false |  | Whether to use GS2-JobQueue to execute the acquire action<br>* Enabled only if enableAtomicCommit is true |
| distributorNamespaceId | string |  |  | "grn:gs2:{region}:{ownerId}:distributor:default" |  ~ 1024 chars | GS2-Distributor Namespace GRN used to execute transactions |
| queueNamespaceId | string |  |  | "grn:gs2:{region}:{ownerId}:queue:default" |  ~ 1024 chars | GS2-JobQueue Namespace GRN used to execute transactions |

### ScriptSetting

Script Setting

In GS2, you can associate custom scripts with microservice events and execute them.
This model holds the settings for triggering script execution.

There are two main ways to execute a script: synchronous execution and asynchronous execution.
Because synchronous execution blocks processing until the script finishes executing,
you can use the script result to stop the API execution or control the API response.

In contrast, asynchronous execution does not block processing until the script has finished executing.
However, because the script result cannot be used to stop the API execution or modify the API response,
asynchronous execution does not affect the API response flow and is generally recommended.

There are two types of asynchronous execution methods: GS2-Script and Amazon EventBridge.
By using Amazon EventBridge, you can write processing in languages other than Lua.



|  | Type | Condition | Required | Default | Value Limits | Description |
| --- | --- | --- | --- | --- | --- | --- |
| triggerScriptId | string |  |  |  |  ~ 1024 chars | GS2-Script script GRN executed synchronously when the API is executed<br>Must be specified in GRN format starting with "grn:gs2:". |
| doneTriggerTargetType | string (enum)<br>enum {<br>&nbsp;&nbsp;"none",<br>&nbsp;&nbsp;"gs2_script",<br>&nbsp;&nbsp;"aws"<br>}<br> |  |  | "none" |  | Asynchronous script execution method<br>Specifies the type of script to use for asynchronous execution.<br>You can choose from "Do not use an asynchronous execution script (none)", "Use GS2-Script (gs2_script)", and "Use Amazon EventBridge (aws)"."none": None / "gs2_script": GS2-Script / "aws": Amazon EventBridge /  |
| doneTriggerScriptId | string | {doneTriggerTargetType} == "gs2_script" |  |  |  ~ 1024 chars | GS2-Script script GRN for asynchronous execution<br>Must be specified in GRN format starting with "grn:gs2:".<br>* Enabled only if doneTriggerTargetType is "gs2_script" |
| doneTriggerQueueNamespaceId | string | {doneTriggerTargetType} == "gs2_script" |  |  |  ~ 1024 chars | GS2-JobQueue Namespace GRN used to execute asynchronous scripts<br>If you want to execute asynchronous execution scripts via GS2-JobQueue instead of executing them directly, specify the GS2-JobQueue Namespace GRN.<br>GS2-JobQueue is generally not required unless you have a specific reason to use it.<br>* Enabled only if doneTriggerTargetType is "gs2_script" |

### LogSetting

Log Output Setting

Manages log output settings.
This type holds the identifier of the log Namespace used to output log data.
The log Namespace ID specifies the GS2-Log Namespace to aggregate and store the log data.
Through this setting, API request and response log data under this Namespace will be output to the target GS2-Log.
GS2-Log provides logs in real time, which can be used for system monitoring, analysis, debugging, etc.



|  | Type | Condition | Required | Default | Value Limits | Description |
| --- | --- | --- | --- | --- | --- | --- |
| loggingNamespaceId | string |  | ✓ |  |  ~ 1024 chars | GS2-Log Namespace GRN to output logs<br>Must be specified in GRN format starting with "grn:gs2:". |

**Related methods:**
createNamespace - Create Namespace
updateNamespace - Update Namespace

### prepareImportUserDataByUserId

Prepare User Data Import by User ID

The data that can be used for import is limited to the data exported by GS2, and old data may fail to import.
You can import data with a user ID different from the one you exported, but if the user ID is included in the payload of the user data, this may not be the case.

You can start the actual import process by uploading the exported zip file to the URL returned in the return value of this API and calling importUserDataByUserId.



#### Request

### prepareUpload

Prepare to upload Data Objects

Creates a new data object and generates a presigned cloud storage URL for uploading the file.
The data object name is optional; if omitted, a UUID is automatically assigned.
You can configure the access scope (public, protected, or private) and specify a list of user IDs allowed to access the object.
If updateIfExists is true and an object with the same name already exists, the existing object's scope and permissions are updated and a re-upload URL is generated instead of returning an error.
The returned presigned URL should be used to PUT the file data directly. After uploading, call DoneUpload to finalize the data object.



#### Request

### updateDataObject

Update Data Objects

Updates the metadata of an existing data object owned by the currently logged-in user.
You can change the access scope (public, protected, or private) and the list of user IDs allowed to access the object.
This operation only updates the access control settings; the file content itself is not modified. To update the file content, use PrepareReUpload instead.

### prepareReUpload

Prepare to re-upload data object

Generates a new presigned cloud storage URL for re-uploading file content to an existing data object.
The data object's status is changed to UPLOADING and a new generation number is assigned.
The previous version of the file is retained in the data object history, allowing you to download older versions by generation number.
After uploading the new file to the returned URL, call DoneUpload to finalize the update.

### prepareReUploadByUserId

Prepare to re-upload data object by User ID

Generates a new presigned cloud storage URL for re-uploading file content to an existing data object owned by the specified user.
The data object's status is changed to UPLOADING and a new generation number is assigned.
The previous version of the file is retained in the data object history.
After uploading the new file to the returned URL, call DoneUpload to finalize the update.

### doneUpload

Report completion of data object upload

Finalizes the data object after the file has been uploaded to the presigned URL obtained from PrepareUpload or PrepareReUpload.
The data object's status is changed from UPLOADING to ACTIVE, and the file metadata (size, generation) is recorded.
If a doneUploadScript is configured in the Namespace settings, the script is executed as a hook after the upload is confirmed.
An error is returned if the data object is not in the UPLOADING state or if the uploaded file was not found.



#### Request

If a doneUploadScript is configured in the Namespace settings, the script is executed as a hook after the upload is confirmed.
An error is returned if the data object is not in the UPLOADING state or if the uploaded file was not found.

### prepareDownload

Prepare data object for download

Generates a presigned cloud storage URL for downloading the latest version of the specified data object.
The data object is specified by its GRN (dataObjectId). Access control is enforced: only the data owner or users listed in allowUserIds can download.

### prepareDownloadByGenerationAndUserId

Prepare data object for download by specifying user ID and generation

Generates a presigned cloud storage URL for downloading a specific version (generation) of the data object.
This allows you to access previous versions of a file that were retained when the data was re-uploaded.
Access control is enforced: only the data owner or users listed in allowUserIds can download.



#### Request

|  | Type | Condition | Required | Default | Value Limits | Description |
| --- | --- | --- | --- | --- | --- | --- |
| namespaceName | string |  | ✓|  |  ~ 128 chars | Namespace name<br>Unique Namespace name. Specified using alphanumeric characters, hyphens (-), underscores (_), and periods (.). |
| userId | string |  | ✓|  |  ~ 128 chars | User ID |
| dataObjectId | string |  | ✓|  |  ~ 1024 chars | Data object GRN |
| generation | string |  | ✓|  |  ~ 128 chars | Data Generation |
| timeOffsetToken | string |  | |  |  ~ 1024 chars | Time offset token |

#### Result

|  | Type | Description |
| --- | --- | --- |
| item | [DataObject](#dataobject) | Data object |
| fileUrl | string | URL to download the file |
| contentLength | long | File size |

### restoreDataObject

Repair management information on data objects

Reconciles the stored metadata of a data object with the actual file state.
If the recorded generation number or content length differs from the actual file, the metadata is updated to match.
This is useful for recovering from inconsistencies that may occur due to partial failures during upload.
Only data objects with ACTIVE status can be restored; an error is returned for other statuses.

### describeDataObjectHistories

List Data Object Histories

Lists all version histories (generations) of a specific data object owned by the currently logged-in user.
Each time a data object's file content is re-uploaded via PrepareReUpload and DoneUpload, a new generation is created and the previous version is recorded in the history.
The history entries contain metadata about each generation, such as the content length and creation timestamp.
Results can be paginated using a page token and limit.

### getDataObjectHistory

Get Data Object History

Retrieves the history entry for a specific generation of a data object owned by the currently logged-in user.
By specifying the generation number, you can access metadata about a particular version of the data object, including its content length and creation timestamp.
This is useful for inspecting past versions of the data object before downloading them via PrepareDownloadByGeneration.



#### Request

|  | Type | Condition | Required | Default | Value Limits | Description |
| --- | --- | --- | --- | --- | --- | --- |
| namespaceName | string |  | ✓|  |  ~ 128 chars | Namespace name<br>Unique Namespace name. Specified using alphanumeric characters, hyphens (-), underscores (_), and periods (.). |
| accessToken | string |  | ✓|  |  ~ 128 chars | Access token |
| dataObjectName | string |  | ✓| UUID |  ~ 128 chars | Data Object Name<br>A unique name identifying the data object. Automatically generated in UUID format by default. Used to reference and manage the uploaded data within the Namespace. |
| generation | string |  | ✓|  |  ~ 128 chars | Generation ID<br>A unique identifier for the specific version of the data object at the time of upload. Corresponds to the generation field in the DataObject and can be used with PrepareDownloadByGeneration to download this specific version. |

#### Result

|  | Type | Description |
| --- | --- | --- |
| item | [DataObjectHistory](#dataobjecthistory) | Data Object History |
