Resources operated in Deloy process

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

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

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

CurrentRankingMaster

Currently Available Master Data

GS2 uses JSON format files for managing master data. By uploading these files, the settings are applied to the server.

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

Note

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

CategoryModel

Category Model

Different rankings can be created for different categories.

Categories can have a minimum and maximum score that can be registered, and scores outside of that range are discarded. When calculating rankings, it is possible to set whether the scores are to be ranked in ascending or descending order, with the smallest scores being ranked higher (ascending order) or the largest scores being ranked lower (descending order).

You can select global or scope as the type of ranking. Global is a ranking where all players see the same results, and Scope is a ranking where each game player has a different result, such as a ranking among friends or a ranking in a guild.

For global ranking, you can set the ranking interval from 15 minutes to 24 hours for each category. Scope rankings reflect the calculate results in real time.

The ranking data has a setting called “generation,” and the registered scores can be reset by changing the generation.
