Reading Time: 5 minutes What is ZIO : ZIO is a cutting-edge framework for creating cloud-native JVM applications. ZIO enables developers to construct best-practice applications that are extremely scalable, tested, robust, resilient, resource-safe, efficient, and observable thanks to its user-friendly yet strong functional core. Difference between Akka and ZIO : Akka and ZIO are both the libraries in Scala for building concurrent, scalable, and fault-tolerant applications. Akka is a Continue Reading

ZIO Streaming Applications, Transformation, and Error Handling

February 21, 2023February 22, 2023Studio-Scalascala

Reading Time: 4 minutes Introduction to Streaming Why do we really need streaming? We can understand the same with the following example. Suppose we have a list of integers and we want to get all the prime numbers and do some further computation on that. In the typical application, we will use ZIO.foreachParN But when we are using the above method we will have two problems:- One Is High Continue Reading

Zio Effects

February 8, 2023February 22, 2023akkaa, kafka, reactive programing, scala, scalatest, spark, Studio-Scala

Reading Time: 5 minutes What are Functional effects? Functional effects refer to the changes or modifications in the state of a program or system as a result of executing a specific function. These effects can include updating variables, creating or destroying objects, modifying data structures, or triggering external events such as sending messages or making HTTP requests. They are an important aspect of functional programming, as they allow developers Continue Reading

Zio Kafka

January 31, 2023February 22, 2023Studio-ScalaKafka Streaming, zio

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

December 30, 2022January 23, 2023Functional Programming, scala, Studio-ScalaFibers, Functional Programming, scala, zio, zio effects

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

December 14, 2022February 22, 2023Studio-ScalaFunctional Programming, scala, Unit Testing, zio, zio effects, zio-test

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

Introduction to ZIO Fibers and Fiber Data Type

September 13, 2022September 13, 2022scala, scala, Studio-ScalaFibers, Functional Programming, scala, zio

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 Test Effects in ZIO | An Introduction to ZIO Test

June 6, 2022June 9, 2022Studio-Scalabuilt-in zio, testing zio effects, zio, zio service, 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

June 3, 2022June 9, 2022Studio-Scalaexception in zio, Futures, 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

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
