Reading Time: 2 minutes It all began in 2012 when the first commit for Scala 3 was made and it was decided to base Scala 3 on DOT. What is DOT? Before we go further into the story, let’s get to know about DOT. DOT, an abbreviation for Dependent Object Types, is a new type-theoretic calculus which models path-dependent types, abstract type members, and it creates a mixture of Continue Reading
Reading Time: 4 minutes In this blog, we will be talking about Spark RDD, Dataframe, Datasets, and how we can transform RDD into Dataframes and Datasets. What is RDD? A RDD is an immutable distributed collection of elements of your data. It’s partitioned across nodes in your cluster that can be operated in parallel with a low-level API that offers transformations and actions. RDDs are so integral to the Continue Reading
Reading Time: 3 minutes In this blog post, we will discuss ZIO fibers and how we can use them. We will also get a quick overview of operations on ZIO fibers. Concurrency in ZIO ZIO is a highly concurrent framework powered by fibers, which are lightweight virtual threads that enable huge scalability when compared to threads, reinforced with resource-safe cancellation, which supports several features in ZIO. This robust concurrency Continue Reading
Reading Time: 4 minutes In this blog, we will read about pattern matching in Scala followed by various types of patterns in match expressions. What is Pattern Matching? Pattern matching in Scala is a powerful mechanism of checking a value against a pattern. Thus, we match a value against a pattern and a successful match deconstructs the value into its constituent parts to be used further. While providing the Continue Reading
Reading Time: 2 minutes Objects are more flexible for certain use cases because they carry both data members and member functions, whereas a function does not have data members. So if there is a requirement to pass data members along with functions, How will we achieve it in functional programming ? The answer is yes, we can achieve it using a closure and a free variable. What is a Continue Reading
Reading Time: 3 minutes ZIO is a Scala library for creating asynchronous, concurrent, and fault-tolerant applications. It is based on the concept of “effects” and provides a powerful and flexible way to express and compose computations that may have side effects, such as reading from a file, writing to a database, or making an HTTP request. ZIO offers a full-featured ecosystem for building applications, including libraries for common tasks Continue Reading
Reading Time: 4 minutes What is Pub/Sub? Cloud Pub/Sub is a message queuing service that allows you to exchange messages between applications and microservices. It’s a scalable, durable, and highly available message-passing system that helps you build event-driven architectures. In this tutorial, we will show you how to use the Google Cloud console to publish and receive messages in Cloud Pub/Sub. We will also provide some tips on how Continue Reading
Reading Time: 2 minutes In this article we will going to cover some introductory part about Scala programming language. Introduction to Scala A contemporary multi-paradigm programming language called Scala was also created to describe common programming patterns in a clear, beautiful, and type-safe manner. Surprisingly It smoothly combines elements of functional and object-oriented languages. Scala as Object Oriented Programming Language Every value is an object in Scala, making it Continue Reading
Reading Time: 2 minutes In this blog post, we will discuss operations on fiber both synchronous and asynchronous with the help of an example. ZIO ZIO is a highly concurrent framework, powered by fibers, which are lightweight virtual threads that achieve massive scalability compared to threads, augmented with resource-safe cancellation, which powers many features in ZIO. However, this powerful concurrency model lets you do more with less, achieving highly Continue Reading
Reading Time: 3 minutes In this blog post, we will discuss fibers in ZIO, and how are they different from threads. Introduction ZIO is a highly concurrent framework powered by fibers that are lightweight virtual threads. They enable tremendous scalability compared to threads and are reinforced with resource-safe cancellation, which supports several features in ZIO. What are Fibers? Fibers are lightweight equivalents of OS threads which represent an ongoing Continue Reading
Reading Time: 2 minutes This article is about ZIO’s support for asynchronous, parallel and concurrent programming and we will see how we can achieve concurrency using fibers model. Since ZIO is built on a fibre concept, we will start by studying what fibres are and how they vary from threads. We will learn the basic operations on fibers including forking them, joining them,and interrupting them. What are Fibers ? Continue Reading
Reading Time: 3 minutes Introduction SOLID is one of the most popular design principles in object-oriented software development. Adopting these practices can prevent code smells, refactoring code, and Agile or Adaptive software development. It was promoted by Robert C Martin and is used across the object-oriented design spectrum. It’s a mnemonic acronym for the following five design principles : I’m going to try to explain SOLID Principles in the Continue Reading
Reading Time: 3 minutes We’ll talk about Apache Beam in this guide and discuss its fundamental concepts. We will begin by showing the features and advantages of using Apache Beam, and then we will cover basic concepts and terminologies. Ever since the concept of big data got introduced to the programming world, a lot of different technologies and frameworks have emerged. The processing of data can be categorized into Continue Reading
