Systems and methods for using a reaction-based approach to managing shared state storage associated with a distributed database

Abstract:

Embodiments are provided for managing shared states of objects associated with a distributed database. According to certain aspects, a reactor machine interfaces with a coordination service that is in communication with the distributed database to coordinate the shared states of the objects. The coordination service notifies the reactor machine when a shared state of an object has changed and, in response, the reactor machine determines a desired state of the object by executing a reactor function. The reactor machine provides the desired state of the object to the coordination service, and the coordination service updates the shared state of the object to reflect the desired state of the object. Accordingly, the logic of the reactor machine is de-coupled from the complexities of the coordination service.
