In the video below, we take a closer look at the thread pool design pattern in Java. Let's get started!
Introduction to Thread Pool Design Pattern [Video]
Functional Programming Is Just a Safety Restriction on Object Orientation
I find that functional languages are an admiration of it's own idealized self. Their pursuit of mathematical (lambda calculus) purity forgets that systems run in the real world and not in theory. Yes, for academia and advancing compilers, they are great where idealized theory is the endeavour. However, their idealism is neglectful of the limitations and realities of computing for commercial development. Why be shamed for wanting to allow side effects and mutating objects? Especially when functional programming just further restricts object orientation.
Limitations
To illustrate my point of limitations within computers, let's use the typical functional programming example of calculating a particular value for the Fibonacci sequence.
Applying Bulkheads and Backpressure Using MicroProfile (Video)
I’ve recorded a video on how to implement bulkheads and backpressure using MicroProfile Fault Tolerance. The idea behind bulkheads is to split applications into several execution units that isolate functionality. In enterprise Java applications, this typically means defining multiple thread pools.
Applying backpressure to clients results in either adding information about the current pressure on the system to the client so that they will react to it, or to explicitly deny the request with a temporary error response.
