Namespace

Namespace is a mechanism that allows multiple uses of the same service for different purposes within a single project. Each GS2 service is managed per namespace. Services within different namespaces are treated as completely independent data spaces, even if they are the same service.

Therefore, it is necessary to create a namespace before starting to use each service.

SendNotificationEntry

Settings for sending notifications

	Type	Condition	Required	Default	Value Limits	Description
userId	string		✓		~ 128 chars	User Id
issuer	string		✓		~ 256 chars	Notification source service
subject	string		✓		~ 128 chars	Subject
payload	string		✓		~ 1024 chars	Payload
enableTransferMobileNotification	bool		✓	false		Forwarding to mobile push notifications when the user to be notified is offline
sound	string	{enableTransferMobileNotification} == true			~ 256 chars	Name of audio file to be played If enableTransferMobileNotification is true, then enabled

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

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 If enableAutoRun is true, then required
transactionUseDistributor	bool	{enableAtomicCommit} == true	✓	false		Whether to execute transactions asynchronously If enableAtomicCommit is true, then required
commitScriptResultInUseDistributor	bool	{transactionUseDistributor} == true	✓	false		Whether to execute the commit processing of the script result asynchronously If transactionUseDistributor is true, then required
acquireActionUseJobQueue	bool	{enableAtomicCommit} == true	✓	false		Whether to use GS2-JobQueue to execute the acquire action If enableAtomicCommit is true, then required
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
