A quick introduction to Virtual Thread(Loom).
Reading Time: 2 minutes In this article, I will quickly describe “What is a Virtual Thread in Java?”
Concurrency using Scala: Problems vs Tools
Reading Time: 5 minutes When we think about modelling a certain concurrent problem in Scala, There are a lot of tools in terms of libraries and frameworks to choose over vs the type of concurrency Problem. As part of this blog, we will be talking about where these tools can be utilised at their best. On a broad level, we can classify the tools into categories. There are concurrency Continue Reading
Achieving Concurrency with Akka Actors
Reading Time: 3 minutes Java comes with a built-in multi-threading model based on shared data and locks. To use this model, you decide what data will be shared by multiple threads and mark as “synchronized” sections of the code that access the shared data. It also provides a locking mechanism to ensure that only one thread can access the shared data at a time. Lock operations remove possibilities for Continue Reading
Java concurrency: Reentrant Locks
Reading Time: 3 minutes Hello readers! Welcome to another blog in the Java concurrency series. Today, we are going to look at the Reentrant Locks in Java. What it is, how to use it, and mainly, what is the difference between using Reentrant Locks and synchronization. So, let’s dive straight into it. Reentrant Locks Reentrant locks work just like the synchronized locks in java, but have much more facilities Continue Reading
Java Concurrency: Count Down Latches
Reading Time: 2 minutes Hello readers, and welcome to yet another blog in the Java Concurrency series. Today, we are going to look at the CountDownLatch class in Java, what it is and how to use it. So, let’s dive straight into it.
Java Concurrency: Thread Confinement
Reading Time: 3 minutes Hello readers! In this blog, we are going to explore about Thread Confinement, what it means and how do we achieve it. So, let’s dive straight into it.
Java Concurrency: Atomic Variables
Reading Time: 3 minutes In today’s blog, we will be discussing and understanding the use of atomic variables with regards to concurrency in Java. But before understanding atomic variables, let’s understand what do we mean by atomic or atomicity.
Guide to Java 8 Concurrency API using Executors
Reading Time: 3 minutes Working with the Thread class in Java can be very tedious and error-prone. Due to this reason, Concurrency API was introduced back in 2004 with the release of Java 5 and then enhanced with every new Java release.The API is located in package java.util.concurrent. It contains a set of classes that make it easier to develop concurrent (multithreaded) applications in Java. The executor services are one of the most Continue Reading
Knolx – Akka Finite State Machine
Reading Time: < 1 minute Hi all, Knoldus has organized a 30 min session on 17th February 2017 at 4:05 PM. The topic was Akka Finite State Machine. Many people have joined and enjoyed the session. I am going to share the slides and Video here. Please let me know if you have any question related to linked slides.
Akka Persistence using MongoDB – Part I
Reading Time: 3 minutes Akka is a powerful actor based tool kit for Concurrency, Parallelism and Clustering. But for every concurrent applications, Akka actors are not fit because Futures are another alternative for performing Concurrency. Most of the developers follow simple rules for using Future and Actors is “Futures for Concurrency, Actors for State“. In concurrent applications most of the time we are facing race conditions and deadlocks. Because Continue Reading
Scala Future Under The Hood
Reading Time: 3 minutes In the previous post, i was discussing about Scala ExecutionContext. As we know, for multithreading we need to maintain thread pools using ExecutionContext and by default ForkJoinPool is used because for accessing “multi core” processor. There are multiple thread pools are available in our java.util.concurrent.Executors utility class and as per our requirement we can create new one also. After all, Scala have concept of Future. Continue Reading
Java Executor Vs Scala ExecutionContext
Reading Time: 3 minutes Java supports low-level of concurrency and some of rich api’s which is just a wrapper of low-level constructs like wait, notify, synchronize etc, But with Java concurrent packages Scala have high level concurrency frameworks for “which goal to achieve, rather than how to achieve“. These types of programming paradigms are “Asynchronous programming using Futures“, “Reactive programming using event streams“, “Actor based programming” and more. Note: Continue Reading
