GS2-Distributor Deploy/CDK Reference

The template format used when creating stacks with GS2-Deploy, and implementation examples of template output in various languages using CDK

Entities

Resources managed by the Deploy operation

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.

Request

Resource creation and update requests

	Type	Required	Value Limits	Description
name	string	✓	~ 128 chars	Namespace name Namespace-specific name. Specified using alphanumeric characters, hyphens (-), underscores (_), and periods (.).
description	string		~ 1024 chars	Description
transactionSetting	TransactionSetting			Transaction Settings Configuration for controlling how distributed transactions are executed when processing resource distribution. Supports auto-run, atomic commit, and async processing options.
assumeUserId	string		~ 1024 chars	GS2-Identifier User GRN
autoRunStampSheetNotification	NotificationSetting	✓		Push notification when transaction auto-execution is complete(Legacy specification) Configuration for sending push notifications via GS2-Gateway when a transaction completes auto-execution on the server side. This is the legacy specification; use autoRunTransactionNotification for the new specification.
autoRunTransactionNotification	NotificationSetting	✓		Push notification when transaction auto-execution is complete Configuration for sending push notifications via GS2-Gateway when a distributed transaction completes auto-execution on the server side. Notifies the client of the transaction result so it can update the local state accordingly.
logSetting	LogSetting			Log Output Setting Configuration for outputting log data of distributor operations to GS2-Log. By specifying a GS2-Log namespace, API request and response logs for resource distribution, transaction execution, and transaction processing can be collected.

TransactionSetting

Transaction Settings

Transaction Settings control how transactions are executed, their consistency, asynchronous processing, and conflict avoidance mechanisms. 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	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 the execution of transactions atomically * Enabled only if enableAutoRun is true
transactionUseDistributor	bool	{enableAtomicCommit} == true	false		Whether to execute transactions asynchronously * Enabled only if enableAtomicCommit is true
commitScriptResultInUseDistributor	bool	{transactionUseDistributor} == true	false		Whether to execute the commit processing of the script result asynchronously * Enabled only if transactionUseDistributor is true
acquireActionUseJobQueue	bool	{enableAtomicCommit} == true	false		Whether to use GS2-JobQueue to execute the acquire action * 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

NotificationSetting

Push Notification Setting

Configuration for sending push notifications when events occur in GS2 microservices. The push notification here refers to the processing via the WebSocket interface provided by GS2-Gateway, and is different from the push notification of a smartphone. For example, when matchmaking is completed or a friend request is received, the GS2-Gateway can send a push notification via the WebSocket interface, and the game client can detect the change of the state.

GS2-Gateway’s push notifications can be used to forward notifications to mobile push notification services when the destination device is offline. By properly utilizing mobile push notifications, you can implement a flow in which players are notified even if they exit the game during matchmaking and later return to it.

Type

Condition

Required

Default

Value Limits

Description

gatewayNamespaceId

string

“grn:gs2:{region}:{ownerId}:gateway:default”

~ 1024 chars

GS2-Gateway namespace to use for push notifications

Specify the GS2-Gateway namespace ID in GRN format starting with “grn:gs2:”.

enableTransferMobileNotification

bool?

false

Whether to forward the notification as a mobile push notification

When an attempt is made to send this notification and the destination device is offline, specify whether it should be forwarded as a mobile push notification.

sound

string

{enableTransferMobileNotification} == true

~ 1024 chars

Sound file name to be used for mobile push notifications

The sound file name specified here is used when sending mobile push notifications, and you can send notifications with a special sound.

* Enabled only if enableTransferMobileNotification is true

enable

string (enum)
enum {
“Enabled”,
“Disabled”
}

“Enabled”

Whether to enable push notifications

Definition	Description
“Enabled”	Enabled
“Disabled”	Disabled

LogSetting

Log Output Setting

Manages log output setting. 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 Must be specified in GRN format starting with “grn:gs2:”.

CurrentDistributorMaster

Currently active Distributor Model master data

This master data defines the Distributor Models currently active within the namespace. GS2 uses JSON format files for managing master data. By uploading these files, the master data are updated on the server.

To create JSON files, GS2 provides a master data editor within the management console. Additionally, you can create tools better suited for game operations and export JSON files in the appropriate format.

Note

Please refer to GS2-Distributor Master Data Reference for the JSON file format.

DistributorModel

Distributor Model

A Distributor Model is an entity that defines the policy applied when acquiring resources beyond the inventory capacity. By processing acquisitions through GS2-Distributor, overflow resources can be forwarded as GS2-Inbox messages.
