One approach to scaling services is to run expensive jobs in the background and wait for the results by using Java's CompletableFuture interface. Often establishing what functionalities we need or translating unclear client's desires into rigid rules is already half of the success. In this article, I propose an approach to implementing a non-blocking state machine with the Spring Integration framework. Figure 1: Representation of a door using a state machine. The state machine in Figure 1 has: a set of states: Open, Closed . The action will call the TaskService and update the JPA entity. Easy to use flat one level state machine for simple use cases. As an example, the following state machine diagram shows the states that a door goes through during its lifetime. The actions available will depend on the type of gameplay but typical actions include things like idling, walking, running, jumping, etc. Spring Statemachine. . Protected software's state is distributed throughout the processor. Turing Machines: An Introduction For a state q and two strings u and v over the tape alphabet Γ, we write u q v for the configuration where the current state is q, the current tape contents is uv, and the current head location is the first symbol of v. For instance, 1011 q7 0111 represents the configuration when the tape is 10110111, the .
