GS2-Gateway 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 targeted 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.

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 * Enabled if enableAutoRun is true
transactionUseDistributor	bool	{enableAtomicCommit} == true	false		Whether to execute transactions asynchronously * Enabled if enableAtomicCommit is true
commitScriptResultInUseDistributor	bool	{transactionUseDistributor} == true	false		Whether to execute the commit processing of the script result asynchronously * Enabled if transactionUseDistributor is true
acquireActionUseJobQueue	bool	{enableAtomicCommit} == true	false		Whether to use GS2-JobQueue to execute the acquire action * Enabled 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

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:”.
