Namespace

Namespace is a mechanism that allows multiple uses of the same service for different purposes within a single project. Basically, GS2 services have a layer called namespace, and different namespaces are treated as completely different data spaces, even for the same service.

Therefore, it is necessary to create a namespace before starting to use each service.
