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	Default	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
enableAwaitExchange	bool		false		Whether to enable exchanges that require a waiting time before receiving results When enabled, exchange rate models with `await` timing type can be used. These exchanges require real-time to elapse before rewards can be claimed, enabling crafting or production mechanics where players must wait for the result.
enableDirectExchange	bool		true		Allow direct exchange API calls When enabled, clients can call the exchange API directly to perform resource exchanges. When disabled, exchanges can only be triggered via transaction actions (transactions), providing tighter server-side control over when exchanges occur.
transactionSetting	TransactionSetting	✓			Transaction Setting Configuration for controlling how distributed transactions are executed when processing exchange operations. Supports auto-run, atomic commit, and async processing options.
exchangeScript	ScriptSetting				Script to run when an attempt is made to perform an exchange Script Trigger Reference - `exchange`
incrementalExchangeScript	ScriptSetting				Script to run when an attempt is made to perform an incremental exchange Script Trigger Reference - `incrementalExchange`
acquireAwaitScript	ScriptSetting				Script setting executed when the waiting period completes and the reward is about to be acquired in an await-type exchange Script Trigger Reference - `acquireAwait`
logSetting	LogSetting				Log Output Setting Configuration for outputting log data of exchange operations to GS2-Log. By specifying a GS2-Log namespace, API request and response logs for exchange, incremental exchange, and await operations can be collected.

TransactionSetting

Transaction Setting

Transaction Setting controls how transactions are executed, including 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 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 * Applicable only if enableAutoRun is true
transactionUseDistributor	bool	{enableAtomicCommit} == true	false		Whether to execute transactions asynchronously * Applicable only if enableAtomicCommit is true
commitScriptResultInUseDistributor	bool	{transactionUseDistributor} == true	false		Whether to execute the commit processing of the script result asynchronously * Applicable only if transactionUseDistributor is true
acquireActionUseJobQueue	bool	{enableAtomicCommit} == true	false		Whether to use GS2-JobQueue to execute the acquire action * Applicable 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. Synchronous execution blocks processing until the script has finished executing. Instead, you can use the script’s execution results to halt API execution or control the API’s response content.

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

Must be specified in GRN format starting with “grn:gs2:”.

doneTriggerTargetType

String Enum
enum {
  “none”,
  “gs2_script”,
  “aws”
}

“none”

How to execute asynchronous scripts

Specifies the type of script to use for asynchronous execution.
You can choose from “Do not use asynchronous execution (none)”, “Use GS2-Script (gs2_script)”, and “Use Amazon EventBridge (aws)”.

Definition	Description
“none”	None
“gs2_script”	GS2-Script
“aws”	Amazon EventBridge

doneTriggerScriptId

string

{doneTriggerTargetType} == “gs2_script”

~ 1024 chars

GS2-Script script GRN for asynchronous execution

Must be specified in GRN format starting with “grn:gs2:”.

* Applicable only if doneTriggerTargetType is “gs2_script”

doneTriggerQueueNamespaceId

string

{doneTriggerTargetType} == “gs2_script”

~ 1024 chars

GS2-JobQueue namespace GRN to execute asynchronous execution scripts

If you want to execute asynchronous execution scripts via GS2-JobQueue instead of executing them directly, specify the GS2-JobQueue namespace GRN.
There are not many cases where GS2-JobQueue is required, so you generally do not need to specify it unless you have a specific reason.

* Applicable only if doneTriggerTargetType is “gs2_script”

LogSetting

Log Output Setting

Log Output Setting defines how log data is exported. This type holds the GS2-Log namespace identifier (Namespace ID) used to export log data. Specify the GS2-Log namespace where log data is collected and stored in the GRN format for the Log Namespace ID (loggingNamespaceId). Configuring this setting ensures that log data for API requests and responses occurring within the specified namespace is output to the target GS2-Log namespace. GS2-Log provides real-time logs that can be used for system monitoring, analysis, debugging, and other operational purposes.

	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:”.

CurrentRateMaster

Currently active Rate Model master data

This master data describes the definitions of Rate Models currently active within the namespace. GS2 uses JSON format files for managing master data. By uploading these files, the master data settings 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 Master Data Reference of GS2-Exchange for the JSON file format.

RateModel

Exchange Rate Model

Exchange Rate Model is an entity that defines the rate used to exchange one resource for another.

In addition to the rate at which a resource can be exchanged immediately, a rate can also be set at which a resource can be exchanged after a certain amount of time in real time has elapsed. Exchange rates that after a certain period of real time has elapsed can further define the resources required to perform an immediate exchange.

IncrementalRateModel

Incremental Cost Exchange Rate Model

Normal exchange rates always provide exchanges at a constant rate. With incremental exchange rates, you can define a rate that increases in cost as the number of exchanges increases. For example, the first exchange is performed at a rate of 1:1, but the second exchange is performed at a rate of 2:1. By defining such a rate, you can increase the value of the resources obtained by the player as the game progresses.

The number of exchanges can be reset after a certain period of real time has elapsed. This is useful for resetting the number of exchanges on a daily or weekly basis.
