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

A system for interfacing with a coordination service to manage shared states of objects associated with a distributed database having a plurality of computing devices, the coordination service in communication with the distributed database to coordinate the shared states of the objects, the system comprising:

• a reactor machine executed by one or more computer processors and adapted to interface with the coordination service, the reactor machine configured to:
• receive, from the coordination service in communication with the distributed database, a notification that a shared state of an object stored within the distributed database has changed,
• in response to receiving the notification, retrieve an observed state of the object from the coordination service,
• determine a desired state of the object based on the observed state of the object, and
• send the desired state of the object to the coordination service, wherein the coordination service updates the shared state of the object to reflect the desired state of the object.

A system for managing shared states of objects associated with a distributed database having a plurality of computing devices, comprising:

• a coordination service comprising a memory for storing the shared states of the objects, the coordination service in communication with the distributed database to coordinate the shared states of the objects;
• a reactor machine executed by one or more computer processors and adapted to interface with the coordination service, the reactor machine configured to:
• receive, from the coordination service, a notification that a shared state of an object stored within the distributed database has changed,
• in response to receiving the notification, retrieve an observed state of the object from the coordination service,
• determine a desired state of the object based on the observed state of the object, and
• send the desired state of the object to the coordination service, wherein the coordination service updates the shared state of the object according to the desired state of the object.
