GS2-Script 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 managed 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.

Request

name	string	✓	~ 128 chars	Namespace name Namespace-specific name. Specified using alphanumeric characters, hyphens (-), underscores (_), and periods (.).

transactionSetting	TransactionSetting			Transaction Setting Settings for distributed transactions used when scripts return transaction actions.
logSetting	LogSetting			Log Output Setting Specifies the GS2-Log namespace for outputting API request and response logs. Used for tracking script invocations and their results.

TransactionSetting

Transaction Setting

Transaction Setting controls execution methods, consistency, asynchronous processing, and conflict avoidance mechanisms of transactions. Combining features like AutoRun, AtomicCommit, asynchronous execution using GS2-Distributor, batch application of script results, and asynchronous processing of 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 only if enableAutoRun is true
transactionUseDistributor	bool	{enableAtomicCommit} == true	false		Whether to execute transactions asynchronously * Enabled only if enableAtomicCommit is true
commitScriptResultInUseDistributor	bool	{transactionUseDistributor} == true	false		Whether to execute the commit processing of the script result asynchronously * Enabled only if transactionUseDistributor is true
acquireActionUseJobQueue	bool	{enableAtomicCommit} == true	false		Whether to use GS2-JobQueue to execute the acquire action * Enabled 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

LogSetting

Log Output Setting

Log Output Setting defines how log data is exported. This type holds the GS2-Log namespace identifier (Namespace ID), which is 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:”.

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.

Request

Resource creation and update requests

	Type	Required	Default	Value Limits	Description
namespaceName	string	✓		~ 128 chars	Namespace name Namespace-specific name. Specified using alphanumeric characters, hyphens (-), underscores (_), and periods (.).
name	string	✓		~ 128 chars	Script name Script-specific name. Specified using alphanumeric characters, hyphens (-), underscores (_), and periods (.).
description	string			~ 1024 chars	Description
script	string	✓		~ 5242880 chars	Lua Script
disableStringNumberToNumber	bool		false		Do not convert strings consisting only of numbers to numbers

GetAttr

Resource creation results that can be retrieved using the !GetAttr tag
