Executing isolated tasks with the scheduler pattern

An application behaving deterministically can play a critical role in its success. A scheduler pattern can help to achieve the desired goal.

Motivation

Although schedulers are sometimes poorly designed to keep the application busy, their main purpose is important. The importance of using patterns comes to light more with microservices or distributed approaches in which the system is required to behave predictably. The general goal is to determine when a specific task is performed so that the underlying resources are properly used or a budget estimate can be created for the required resources described in site reliability engineering.

Sample code

The following example brings us to temperature measurement. Every vehicle contains temperature sensors in a mechanical or digital form. Temperature sensors play a key role in vehicle operation (Example 6.13):

public static void main (String [] args) throws Exception {
