GS2-Deploy/CDK Reference of GS2-StateMachine

Template format used to create GS2-Deploy stacks and examples of template output implementation in various languages using CDK

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.

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

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.
