Zio Kafka

Reading Time: 4 minutes ZIO Kafka is a library in Scala, a distributed streaming platform for building real-time data pipelines and streaming applications. It provides a very high-level, composable API built on top of the Kafka Consumer and Producer APIs, allowing developers to write type-safe, functional code for working with Kafka. It is part of the ZIO ecosystem, which is a library for building concurrent, fault-tolerant, and high-performance systems Continue Reading

How To Perform Operations on ZIO Fibers

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

How to write unit test in Scala ZIO

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

Synchronous and Asynchronous Fibers in ZIO

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

Introduction to ZIO Fibers and Fiber Data Type

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

How To Achieve Concurrency in ZIO?

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

How to Test Effects in ZIO | An Introduction to ZIO Test

Reading Time: 4 minutes In this blog, we’ll understand how to test ZIO effects using the ZIO Test library. Also, we’ll learn about some of the common assertions and a nice feature of ZIO Test which is test aspects. What is ZIO Test? ZIO Test is a testing library that makes it easy to test effectual programs. It treats effects as first class values and leverages the full power Continue Reading

Exceptions and Futures in Zio

Reading Time: 3 minutes ZIO is an open-source library that delivers a better “Future” for asynchronous and concurrent programming in Scala. Similarly, we can’t retry a Future in the event of failure, like we can for ZIO, because a Future isn’t a blueprint for doing something—it’s an executing computation. So if a Future fails, there is nothing else to do. We can only retrieve the failure. The central “type Continue Reading

What are Zio Effect Constructors?

Reading Time: 3 minutes In this blog post, we will discuss about ZIO effect constructors and how we can use them. Then we’ll take a look at Effect constructors for pure computations and side-effecting computations. Zio Effect Constructors A functional effect is a template for a concurrent workflow. The template which is mostly descriptive in nature, used to test for any side effects. Such as database interaction, logging, data Continue Reading

Experimenting with recursion and ZIO

Reading Time: 4 minutes If you’re already comfortable with recursion, you can skip the first part introducing tail-recursion and go directly to the ZIO section. Introduction: recursion and functional programming Recursion is one of the main techniques used in functional programming to replace an iterative loop. One of the most common examples is the Fibonacci computation or factorial computation. For this experiment, we will focus on an even simpler Continue Reading

Want to learn about Standard ZIO Services?

Reading Time: 3 minutes In this blog, we’ll talk about Standard ZIO Services and why it’s useful for us as programmers and how we can use them.Services provide well-defined interfaces that can be implemented differently in testing environments and production environments. Build-in services When we use the services we don’t need to provide their corresponding environment explicitly. ZIO provides built-in live version of ZIO services to our effects, so Continue Reading

Sequential Composition in Scala Zio

Reading Time: 3 minutes Overview In this blog we will discuss how the concurrent workflows can be simplified and can be executed in a sequential manner using flatmap and other sequential composition.The flatmap method of ZIO effect represents sequential composition where output of first effect act as input for the second. Further in this blog we will discuss some more operators that can define further workflow. You need to Continue Reading

How to Compose Layers in Zio

Reading Time: 5 minutes Introduction According to ZIO documentation, we know ZIO is a library for asynchronous and concurrent programming that promotes pure functional programming. The core of the ZIO library provides a powerful effect type ZIO inspired by Haskell’s IO monad. The value of this type doesn’t do anything itself. It is just a description of something that should be done.ZIO runtime system is responsible for actually doing what is Continue Reading
