Reading Time: 2 minutes Hello everyone! in the previous blog of Apache Calcite we discussed how Apache Calcite helps you to parse the database query and some basics. In this blog, we will discuss how to generate the logical plan of the database query you have written. What is logical plan A logical plan is a relational expression with only a logical operator. Logical algebra has no implementation of the relational operator and therefore Continue Reading
Reading Time: 4 minutes A safer way to build robust front-end web applications! http://www.scala-js.org/ In this blog, we are gonna utilizing a whole lot of features of Scala to build a simple front-end application using Scala.js. So, let’s get it started- Step-1: – Creating an sbt project Create a folder named scala-js-example and inside it create a build.sbt. build.sbt Now, create a new folder named as a project inside Continue Reading
Reading Time: < 1 minute Intersection Type is a type which is the mixin of multiple types.
The intersection types of two different type A and B would be written as A & B in Scala3
Reading Time: 4 minutes If you’re new to the concept of type classes I suggest you read my other article explaining them. The Cats library makes extensive use of type classes and a basic understanding is a prerequisite for this article. In previous articles, we talked about Semigroups and Monoids, which are abstractions that let us combine values of the same type together. In this post, we’ll take a look at Functors, which Continue Reading
Reading Time: < 1 minute Hello folks, We have released another video on Scala3 series which talks about a new type i.e. Union Types. Union Type is a type which is one of a set of other type, or a type of a variable or expression which can consist of multiple types. And the main reason for introducing Union Types in Scala is that for every set of types, we Continue Reading
Reading Time: 4 minutes While exploring Cats I learned about Monads and its different instances available for use and now I’m here sharing all of that with you all. 😊 In today’s blog, we will be exploring Eval Monad in Cats. Model of Evaluation From the model of evaluation, I am referring to the way that the value will be evaluated. Generally, we have two of them i.e. Eager Continue Reading
Reading Time: 3 minutes Today we are going to explore Id Monad in Cats. If you don’t know about Monad I’ll suggest you go through this blog and then read this for better understanding. What is Id Monad? According to the referenced book: Id is actually a type alias that turns an atomic type into a single-parameter type constructor. Ahan! So, did you understand something? Let me explain it Continue Reading
