GS2-Dictionary 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.

TransactionSetting

Transaction Setting

Transaction Settings control how transactions are executed, 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 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

ScriptSetting

Script Setting

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. Because synchronous execution blocks processing until the script finishes executing, you can use the script result to stop the API execution or control the API response.

In contrast, asynchronous execution does not block processing until the script has finished executing. However, because the script result cannot be used to stop the API execution or modify the API response, asynchronous execution does not affect the API response flow and 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.

Type

Condition

Required

Default

Value Limits

Description

triggerScriptId

string

~ 1024 chars

GS2-Script script GRN executed synchronously when the API is executed

Must be specified in GRN format starting with “grn:gs2:”.

doneTriggerTargetType

string (enum)
enum {
  “none”,
  “gs2_script”,
  “aws”
}

“none”

How to execute asynchronous scripts

Specifies the type of script to use for asynchronous execution.
You can choose from “Do not use asynchronous execution (none)”, “Use GS2-Script (gs2_script)”, and “Use Amazon EventBridge (aws)”.

Definition	Description
“none”	None
“gs2_script”	GS2-Script
“aws”	Amazon EventBridge

doneTriggerScriptId

string

{doneTriggerTargetType} == “gs2_script”

~ 1024 chars

GS2-Script script GRN for asynchronous execution

Must be specified in GRN format starting with “grn:gs2:”.

* Enabled only if doneTriggerTargetType is “gs2_script”

doneTriggerQueueNamespaceId

string

{doneTriggerTargetType} == “gs2_script”

~ 1024 chars

GS2-JobQueue namespace GRN to execute asynchronous execution scripts

If you want to execute asynchronous execution scripts via GS2-JobQueue instead of executing them directly, specify the GS2-JobQueue namespace GRN.
There are not many cases where GS2-JobQueue is required, so you generally do not need to specify it unless you have a specific reason.

* Enabled only if doneTriggerTargetType is “gs2_script”

LogSetting

Log Output Setting

Manages log output setting. 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 Must be specified in GRN format starting with “grn:gs2:”.

CurrentEntryMaster

Currently active Entry Model master data

This master data defines the Entry Models currently active within the namespace. GS2 uses JSON format files for managing master data. By uploading these files, the master data are updated on the server.

To create JSON files, GS2 provides a master data editor within the management console. Additionally, you can create tools better suited for game operations and export JSON files in the appropriate format.

Note

Please refer to GS2-Dictionary Master Data Reference for the JSON file format.

EntryModel

Entry Model

An Entry Model is master data that defines what can be recorded in the Dictionary within GS2-Dictionary. Each Entry Model represents a type of entity recorded in the Dictionary, such as monsters, items, or avatar parts.

The possession state of an entry is managed as a binary state—recorded or not recorded—and there is no concept of quantity or stacking for a single Entry Model.

	Type	Required	Value Limits	Description
entryModelId	string	*	~ 1024 chars	Entry Model GRN * Set automatically by the server
name	string	✓	~ 128 chars	Entry Model name
metadata	string		~ 2048 chars	Metadata Arbitrary values can be set in the metadata. Since they do not affect GS2’s behavior, they can be used to store information used in the game.
