Entities

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.

ScriptSetting

Script settings

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 execution result to stop the execution of the API or to tamper with the result of the API.

In contrast, asynchronous execution does not block processing until the script has finished executing. Since the script result cannot be used to stop the API execution or modify the API response, asynchronous execution does not affect the API’s response flow. For this reason, asynchronous execution 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.

LogSetting

Log setting

This type 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

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
