Using Apache Pulsar and Spring Boot for Real-Time Stream Processing

Real-time stream processing has become a critical component of modern data-driven applications. Apache Pulsar is an open-source distributed messaging system that provides seamless horizontal scalability and low-latency processing of real-time data streams. Spring Boot is a popular Java framework that simplifies the process of building and deploying production-grade applications. In this article, we will explore how to use Apache Pulsar and Spring Boot for real-time stream processing. 

Getting Started With Apache Pulsar

The first step in building a real-time stream processing application with Pulsar is to set up a Pulsar cluster. A Pulsar cluster consists of one or more brokers that handle incoming data streams and route them to the appropriate consumers. Pulsar provides a simple and straightforward way to set up a cluster using the Pulsar CLI tool.

The Importance of Test-Driven Development in Software Development

Software development has come a long way since the early days of programming. The importance of developing high-quality software has become increasingly important as businesses rely more heavily on technology to drive their operations. One method that has gained traction in recent years is Test-Driven Development (TDD). In this article, we'll explore what TDD is, why it's important, and how to implement it in your software development process.

What Is Test-Driven Development?

Test-Driven Development is a software development technique that emphasizes writing automated tests before writing the actual code. The process starts with writing a test case, then writing the code that satisfies that test case. Once the code has been written, the test is run to ensure that it passes. If the test fails, the code is revised until the test passes. This process is repeated until all the tests have passed and the software is considered complete.
