StaticInstanceThe Global Object Store is a place to store global objects that need to be shared across the application. Depending on the execution environment, this could be the window object in a browser, or the global object in a node environment, or something else in other contexts. The key here is that in some cases static variables are not truly shared because it is possible that a given class might have copies of its code in multiple paths in a deployed application. This approach ensures that no matter how many code copies might exist, there is only one instance of the object in question by using the Global Object Store.
Protected StaticgetReturns the singleton instance of the class. If the instance does not exist, it is created and stored in the Global Object Store. If className is provided it will be used as part of the key in the Global Object Store, otherwise the actual class name will be used. NOTE: the class name used by default is the lowest level of the object hierarchy, so if you have a class that extends another class, the lowest level class name will be used.

Rate limiter singleton for managing API requests across action instances.
limitersis keyed by the caller-suppliedRateLimitKeyaction parameter, so its key space is not bounded at compile time (a dynamic key per record/tenant/timestamp would grow it without bound). Bounded viaMJLruCacherather than a rawMap; theonEvicthook disposes the evictedAPIRateLimiter's RxJS subscription so it doesn't also leak.
