How to convert Spark RDD into DataFrame and Dataset

December 31, 2022January 4, 2023Studio-Scalafunctional programing, Functional Programming, Spark

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

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

Pattern Matching and Its Types in Scala

December 30, 2022January 2, 2023Studio-ScalaFunctional Programming, scala

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

What is a Closure in Scala ? Why it is required ? How to use it ?

December 27, 2022December 28, 2022Studio-Scalaclosure, Functional Programming, scala

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

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

Publish and receive messages in Google Cloud Pub/Sub

November 28, 2022November 30, 2022GCP, JavaFunctional Programming, Gcp

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

Synchronous and Asynchronous Fibers in ZIO

September 28, 2022October 20, 2022Studio-ScalaFibers, Functional Programming, scala, 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
