Reading Time: 3 minutes In continuation of my cucumber series, this blog will help us clear the concept of using cucumber tags and hooks. We will look at some practical approach and how a lot of time can be saved by using different tags and hooks. What are cucumber tags and hooks? Now, tagging is nothing but a simple annotation. So, you can provide your annotation using a conventional Continue Reading
Reading Time: 4 minutes In today’s world we have a lot of data. And this data will only grow more and more in future. According to a study, in 2020, the data produced is abound 44 zettabytes each day. And by 2025, approximately 463 exabytes would be created every 24 hours worldwide. Do you ever imagine how one can store or process this much data ?A solution to this Continue Reading
Reading Time: 5 minutes Data Science, Data Analytics, Big Data, these are the buzz words of today’s world. A huge amount of data is being generated and analyzed every day. So communicating the insights from that data becomes crucial. Charts help visualize the data and communicate the result of the analysis with charts, it becomes easy to understand the data. There are a lot of libraries for angular that Continue Reading
Reading Time: 3 minutes Service mesh is a dedicated infrastructure layer for handling service to service communication.
Basically, it’s a way to control how different micro services deployed on kubernetes will manage secure communication and traffic between them with lot’s of cross-cutting concerns like logging, security, etc.
Reading Time: 6 minutes UI (USER INTERFACE) UI or User Interface is the interface that is the access point where users interact with computers. It is also a way through which users can interact with a website or an application. UI design typically refers to graphical user interfaces but also includes others, such as voice-controlled ones, a keyboard, a mouse, and the appearance of a desktop. UI design considers Continue Reading
Reading Time: 2 minutes In this blog, we will see how to read the Avro files using Flink. Before reading the files, let’s get an overview of Flink. There are two types of processing – batch and real-time. Batch Processing: Processing based on the data collected over time. Real-time Processing: Processing based on immediate data for an instant result. Real-time processing is in demand and Apache Flink is the Continue Reading
Reading Time: 3 minutes In this blog, we are going to use kinesis as a source and kafka as a consumer. Let’s get started. Step 1: Apache Flink provides the kinesis and kafka connector dependencies. Let’s add them in our build.sbt: Step 2: The next step is to create a pointer to the environment on which this program runs. Step 3: Setting parallelism of x here will cause all Continue Reading
Reading Time: 5 minutes Distributed stream processing engines have been on the rise in the last few years, first Hadoop became popular as a batch processing engine, then focus shifted towards stream processing engines. Stream processing engines can make the job of processing data that comes in via a stream easier than ever before and by using clustering can enable processing data in larger sets in a timely manner. Continue Reading
Reading Time: 4 minutes Code quality is one of the most important aspects of programming world. As it impacts our overall software quality i.e., how safe, secure, and reliable our codebase is. Code quality is not only to perform efficiently but also to make code more readable. Essentially, code that is considered good:
Reading Time: 2 minutes Now a days everyone is talking about WebAssembly. In this blog, I will explain how you can get started with Rust and WebAssembly fast with a simple template. But before we start, lets discuss what is webassembly, why Rust should be preferred for it. What is WebAssembly: We can think of webassembly as a type of bytecode that can be generated from any language. That Continue Reading
Reading Time: 6 minutes Now keep in mind that the versions of this project may change in future as the application grows. I will try my best to keep this blog updated but in case i am not able to, below in the references you will find the github link of this project. Follow the README.md and you will be able to run the project. References : https://github.com/digital-asset/daml-on-fabric – Continue Reading
Reading Time: 3 minutes In this blog we will talk about, What is CQRS and Why the requirement of using CQRS occurs. CQRS stands for Command, Query, Responsibility Segregation. As we know Segregation means1. Separating a Microservice for each logic business operation from a Monolith. 2. In same way, Segregate the read side from the write side. This helps in increasing the performance, scalability, and security. Tradition Approach A Continue Reading
Reading Time: 4 minutes In my previous blogs I discussed about akka-streams , materialization and graphs in akka-stream . It was so easy to create sources, sinks and flows and connect them using methods and create runnable graphs. Now consider a situation where I’m getting data from Kafka and want to push it in Cassandra or Elasticsearch ? How to create such source or flow or sink that can Continue Reading
