Java Magazine: Reactive Programming

By Java Magazine Editor Andrew Binstock

Reactive programming is a term that means slightly different things to different people. Central to the concept, though, is a model of computing that is alerted to certain kinds of events, can process or ignore those events, and works with the event source to manage the number of events to be processed.

In practice, this model rests on several technologies: a message-passing framework, a subscription-based notification system, and an asynchronous execution of the event-driven tasks. The benefit is a loosely coupled implementation that is scalable and tends to isolate failures. The scalability here refers to the ability to scale horizontally quickly, and it anticipates handling the number of events associated with big data—millions to billions of incoming events. This aspect, in particular, is what makes the reactive model different from its familiar forebear, the event loop in GUI development.

In this issue, we provide an overview of reactive development (page 16) and then do a deep dive into RxJava (page 32), one of the leading libraries for developing reactive applications on the JVM. We follow that up by looking at the reactive capabilities built into the most recent release of Spring 5.0 (page 61). Finally, we examine a slightly different model for developing CRUD applications, called Command Query Responsibility Segregation, or CQRS (page 69), which while not reactive per se implements an approach that overlaps with reactive programming.

It might seem that reactive programming is a design that would lead naturally to microservice implementation. And indeed it is.

New-age IT skills can double your pay

If you have some of the new-age tech skills, not only are you likely to be hired much faster, you could also earn far better salaries.

Terms like R, Julia, Hadoop, Scrum Master and DevOps may sound alien to most people, but these are some of the hot skills that companies are looking for. A youngster who has just started out and has learnt R, a popular programming language used for statistical computing to derive insights from data, gets an average salary of Rs 8 lakh a year, according to data, an online education provider of professional certification training or Certified Java Training in Mumbai. In comparison, the average salary for a regular fresher in an IT company is Rs 3.5 lakh.

A mobile app developer or a Hadoop developer (Hadoop is a programming framework that supports the processing of large amounts of data in a widely distributed computing environment) can also get a similar salary. Age is not a factor here, it just depends on whether you have picked up the skills.

These skills reflect the big shifts in the kind of software being used inside large firms today. This has been driven by the dramatic increase in mobile devices, the big jump in digital data, the need to analyze this data, and the phenomenon called cloud computing -- use of remote servers hosted on the internet to store, manage, and process data, rather than a local server or a personal computer. Added to this is the emergence of what is called the internet-of-things - the trend to get everyday objects, be it a toaster, fridge, light fitting or an industrial machine, to communicate their status with remote computers or Smartphone’s or even with one another.

"These are deep technology shifts changing the game for businesses. Five years ago, Java, C++ were sought-after skills, but IT companies are today looking at diversity in their tech talent pool to improve business conversation with their customers," said Kashyap Dalal.

Sachin Gupta, co-founder of online programing platform HackerEarth, said R programing provides a very good way to quickly prototype and visualize data. "Its libraries in statistics and mathematics give a lot of power to data scientists to quickly manipulate data. Julia, which started as a scientific computing language, is gaining traction in the data sciences domain. Python, a programing language for data sciences, continues to be the language of choice after R because of its versatility," he said.

Dalal said that a Hadoop skill set will get a developer 25% higher compensation compared to just having a Jgava skill set. An iOS developer can expect way higher salaries than an Android developer, partly because such skills are in short circulation. Gupta's data showed that an iOS developer with 2-4 years of experience gets paid between Rs 12.5 lakh and Rs 25 lakh, while an Android developer with a similar experience gets paid Rs 15 lakh to Rs 18 lakh.

Gupta said there's a lot of demand for full-stack developers, the supercoders who understand database programing, have knowledge of HTML, CSS (which describes how HTML elements are to be displayed on screen) and JavaScript and have experience in cloud deployment solutions like AWS.
