Read CRUD Action

MillieJS provides the an interface for Read actions that sync between a replica store and the upstream source. The sync action in operation today is rudimentary, however, with no real fault-tolerance, scalability, or concurrency (see below).

            Millie->>Replica: read Entities (from request)

    and
        critical Read from Replica with requested payload
            Millie->>Source: read Entities (from request)
        end
    end
    Replica->>Client: return fetched Replica Entities to requesting client
    Source-->>Client: eventually return fetched Source Entities to requesting client

Future Plans

This first iteration of MillieJS only covers basic sync capabilities. This is by all means a minimally-viable product ("MVP") with intentional limitations in place, however, future scale is coming.
