A brief overview of the Fork/Join Framework in Java

IntroductionThe Fork/Join framework is a framework to solve a problem using a concurrent divide-and-conquer approach. They were introduced to complement the existing concurrency API. Before their introduction, the existing ExecutorService implementations were the popular choice to run asynchronous tasks, but they work best when the tasks are homogenous and independent. Running dependent tasks and combining their results using those implementations were not easy. With the introduction of the Fork/

Java Tips: Creating a Monitoring-friendly ExecutorService

In this article we will be extending an ExecutorService implementation with monitoring capabilities. This monitoring capability will help us to measure a number of pool parameters i.e., active threads, work queue size etc. in a live production environment. It will also enable us to measure task execution time, successful tasks count, and failed tasks count.Monitoring LibraryAs for the monitoring library we will be using Metrics. For the sake
