Comparing Data Streaming Frameworks | Scala

Reading Time: 4 minutes In this Era of Technology, where the amount of data is growing exponentially and every bit of data holds value. Even, according to some reports, the number of bytes being generated and stored till now in the world has already exceeded the star counts in the sky. As every bit is useful so, it is very important to store them without losing any bit. When Continue Reading

Pattern Matching In Scala | Basic & Advanced Pattern Match

Reading Time: 5 minutes Pattern Matching is one of the most powerful features in SCALA. Unlike in C, C++, JAVA we have a switch statement, Scala has a rich set of “patterns” for matching. So, In this blog, we’ll discuss various types of pattern matching followed by some advanced concepts in Pattern Matching in Scala. Pattern Matching In Scala – Pattern Matching is a mechanism of checking a value Continue Reading

Akka Streams | Three Basic Components

Reading Time: 3 minutes Akka, a free open source toolkit simplifying the construction of concurrent and distributed system/application. We have already deal with Akka Actors where we learnt about the Akka Actors and their Behaviors. But Actors can be seen dealing with with Sequence of Data where they send or receive series of messages. So, In this blog we discuss Akka Stream in bit detail. What is Akka Streams Continue Reading

Read Model and Write Model | CQRS | Reactive Architecture

Reading Time: 2 minutes Read Model and Write model…what they are and from where they have been driven. In this blog we’ll discuss about CQRS, read model and write model in brief. CQRS – What, Why and How … ? Till the time we have used a number of different architectures, patterns and implementations that revolve around the core concept of Command Query separation (CQS). The core ideas behind Continue Reading

Synchronous Testing In Akka ToolKit | Testing Classic Akka Actors

Reading Time: 3 minutes Akka, a free open source toolkit simplifying the construction of concurrent and distributed systems/applications. In this blog, we are gonna discuss Testing the Akka Actors Synchronously. Usually, we people say that testing the Akka Actors is a bit confusing and tricky too, but it isn’t. Coming to the types of testing in Akka Toolkit, we have two types of testing i.e. Synchronous Testing and Asynchronous Continue Reading

Collections in Scala (Part-2) | Set

Reading Time: 4 minutes Collections in Scala systematically distinguish between mutable and immutable collections. In the previous blog, we had covered – An Overview of Collections and its types in Scala (Im)Mutability in Scala You may go through the Collections And (Im)Mutability in Scala (Part-1). So, In this Blog we will discuss Scala Set in detail. Set – Scala Sets are iterables that does not contain any duplicate element. Continue Reading

CAP Theorem | Building Scalable Systems | Reactive Architecture

Reading Time: 3 minutes CAP Theorem, a Distributed System must account for this theorem which means when two or more systems try to connect with each other they need to account this Theorem. In this blog, we are gonna discuss about this theorem and how we have to sacrifice any factor while communicating with another system. Apart from this we’ll also discuss some other related terminologies and theorems. CAP Continue Reading

Performance v/s Scalability in Reactive Microservices

Reading Time: 2 minutes Performance and Scalability are the two main factors that come into account when creating a Distributed System. When people talk about these two terminologies they very often use these two words synonymously. However, they mean different things. As there’s a lot of misunderstanding so in this blog we’ll discuss Performance and Scalability, their differences and relation if any. Performance – Performance is all about optimizing Continue Reading

Akka Toolkit | Creating your First Akka Actor | Scala

Reading Time: 3 minutes Akka, a free open source toolkit simplifying the construction of concurrent and distributed system/application. In this blog we are gonna discussing about Akka, Actors and finally creating and running our first actor. Akka – Again, it is a free and open-source toolkit and runtime. It is used to develop highly concurrent, distributed, and fault-tolerant message-driven applications on the JVM(Java Virtual Machine). It includes features for Continue Reading

Collections And (Im)Mutability in Scala (Part-1)

Reading Time: 5 minutes Collections in Scala systematically distinguish between mutable and immutable collection. In this blog we are gonna discuss Mutability of Immutable collections in Scala. Collections in Scala – These are nothing, just like containers. Those containers can be Sequence, Set or Map. Scala provides a rich set of Collections library which can be mutable or immutable. In Scala, Collections are classified into 3 categories with the Continue Reading

DAO | Abstraction of the Application/Business layer from the persistence layer

Reading Time: 3 minutes DAO…. In this blog we’ll be learning about data access objects , it’s pros and cons and implementation in Scala Language. What is DAO …. ? It’s an abbreviation of Data Access Object. It is a structural pattern that provides an abstract API to isolate the application/business layer from the persistence layer . This Layer could be a database or any other persistence mechanism The main purpose Continue Reading
