Functional Java: It’s good to be lazy

Reading Time: 5 minutes In Java, we are often tempted towards writing a code which is executed eagerly. There’s a good reason for that – eager code is easy to write and to reason about. But delaying commitments until the last responsible moment is a good agile practice. When executing the code, we can gain performance by being just a little lazy.  In this blog, we will try to Continue Reading

Reactive Architecture

Reading Time: 2 minutes Recently I got an invitation to present a guest lecture for faculty of Engineering colleges in ABES college of Engineering. I came up with the most trending topic i.e Reactive Architecture. We talked about what is this buzzing keywords and why does it came into existence. Also What are the challenges one were facing and how are the real world problems being solved by using Continue Reading

Why Should Modern Businesses Choose Reactive Systems?

Reading Time: 5 minutes In the world of cloud computing, big data and IoT, system and application requirements have changed by leaps and bounds in recent years. Even the challenges being faced by developers and enterprises today are way different from the ones that they faced, say, a decade or two earlier. Find out why should modern enterprises opt for reactive systems today?

Reactive Java: Understanding Reactive streams

Reading Time: 3 minutes With a lot of buzz in the programming world about “reactive Programming”, a new concept following the same path has been introduced. This is “Reactive streams” backed up by the idea of backpressure. In this blog, we try to understand, what does it mean exactly? What are Reactive Streams? We are here talking about handling streams of data that needs to be handled in an Continue Reading

RAP: The journey from a learning project to a useful product

Reading Time: 4 minutes A few months back, I was working on interesting customer engagement. Lagom was getting popularity, therefore, I and my few team members wanted to explore it to see if it would suit our needs. Just reading its documentation was not enough to get the proper practical hands-on. So we thought to do a project. The idea was that we should not build a dummy project, Continue Reading

Spring WebFlux: Error handling in Reactive Streams

Reading Time: 3 minutes Error handling is one of the ways we ensure we are gracefully handling our failures. While working with streams of data, the Reactive Library Reactor provides us with multiple ways of dealing with situations where we need to handle our errors. In this blog, I wish to discuss a few of them with you.

Spring-Webflux: Testing your Router Functions with WebTestClient

Reading Time: 3 minutes I recently started working on the functional approach of Spring Boot Webflux. You can explore it more on my previous blog on Spring Boot Webflux. It is a new concept and you may not find many useful blogs on it unlike for annotation based controllers. However, going with some trial and error, I have come out with how one can test its router functions along Continue Reading

Spring: Reactive programming in Java

Reading Time: 3 minutes Reactive programming is a programming paradigm that promotes an asynchronous, non-blocking, event-driven approach to data processing. Reactive programming involves modeling data and events as observable data streams and implementing data processing routines to react to the changes in those streams. In the reactive style of programming, we make a request for the resource and start performing other things. When the data is available, we get Continue Reading

Integrating Lagom Service Discovery with Kubernetes

Reading Time: 3 minutes Consider a situation where a microservice is deployed on multiple pods and on condition one pod got restarted with any of the failure reason makes unreachable and at the same time interdependent services are registers its IP for communication. Now, since other pods of the service are alive but not able to communicate makes the communication failure as well as making the failure of every Continue Reading

Working with Project Reactor: Reactive Streams

Reading Time: 4 minutes .The words “Reactive” and “Streams” often go hand in hand. The streams API of Java 8 is a great tool for making your projects Reactive. But that’s not the only stream you can have. In this blog, I’d like to talk about this awesome project called Project Reactor.

Reactivate your streams with Reactive Streams!!

Reading Time: 5 minutes As you all might have known by now that one of the hot topics for quite some time has been streaming of big data. Day after day, we see tons of streaming technologies out there competing with one another. The obvious reason for that, processing big volumes of data is not enough. We need real-time processing of data, especially when we need to handle continuously increasing Continue Reading
