Namespace

A namespace is a mechanism that allows multiple uses of the same service for different purposes within a single project. 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.

TransactionSetting

Transaction settings

Transaction settings control how transactions are executed, their consistency, asynchronous processing, and conflict avoidance mechanisms. Combining features like AutoRun, AtomicCommit, Distributor, batch application of script results, and asynchronous acquisition actions via 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 the execution of transactions atomically * Required if enableAutoRun is true
transactionUseDistributor	bool	{enableAtomicCommit} == true	✓*	false		Whether to execute transactions asynchronously * Required if enableAtomicCommit is true
commitScriptResultInUseDistributor	bool	{transactionUseDistributor} == true	✓*	false		Whether to execute the commit processing of the script result asynchronously * Required if transactionUseDistributor is true
acquireActionUseJobQueue	bool	{enableAtomicCommit} == true	✓*	false		Whether to use GS2-JobQueue to execute the acquire action * Required if enableAtomicCommit is true
distributorNamespaceId	string		✓	“grn:gs2:{region}:{ownerId}:distributor:default”	~ 1024 chars	GS2-Distributor namespace used for transaction execution
queueNamespaceId	string		✓	“grn:gs2:{region}:{ownerId}:queue:default”	~ 1024 chars	Namespace in GS2-JobQueue used to run the transaction

LogSetting

Log Export Settings

Manages log data export settings. 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, and debugging.

	Type	Condition	Required	Default	Value Limits	Description
loggingNamespaceId	string		✓		~ 1024 chars	GS2-Log namespace GRN to output logs

Script

GS2 provides scripts to extend functionality when the standard functions are not sufficient. Scripts can be written in the Lua language.

Scripts can also retrieve data from GS2 services, allowing for flexible processing. Please refer to the documentation for details.

	Type	Required	Default	Value Limits	Description
scriptId	string	✓		~ 1024 chars	Script GRN
name	string	✓		~ 128 chars	Script Name
description	string			~ 1024 chars	Description
script	string	✓		~ 5242880 chars	Lua Script
disableStringNumberToNumber	bool	✓	false		Do not convert strings consisting only of numbers to numbers
createdAt	long	✓	Now		Datetime of creation Unix time, milliseconds Automatically configured on the server
updatedAt	long	✓	Now		Datetime of last update Unix time, milliseconds Automatically configured on the server
revision	long		0	0 ~ 9223372036854775805	Revision
