One-to-many relationships: A one-to-many relationship is a relationship between two models where…

Java supports multi-thread operations. Multithreading is a process of executing two or more threads independently and concurrently with the main()method but sharing the process resources simultaneously. A thread is lightweight because it doesn't allocate separate memory, data, resources, and the environment of that process. A process is created when a…

When we say serverless, as its name says — no server to provision and manage. The reason why we want to build serverless is that we want to deliver products to customers as fast as possible. We want the infrastructure to be reliable, highly available, and scalable. With AWS resources…

By default, Spring Boot transactions are auto-committed. This means that every single SQL statement is treated as its transaction and will commit after execution. Here’s an example that illustrates this behaviour: public void createProduct() { Product prod = new Product(); prod.setDescription("This is…

In this post, we’ll continue exploring the fundamentals of Kafka’s architecture. You may want to revisit this post to understand more about Apache Kafka architecture. 4.5 Message Consumption and Offset Commits When a consumer starts processing a message, it informs the Group Coordinator that it is handling that message. This marks the message as unavailable for…

In a microservices architecture, efficient load balancing is essential to ensure that incoming requests are evenly distributed across multiple instances of a service. This even distribution enhances system performance and fault tolerance. In this article, we will demonstrate how to implement load balancing using Ribbon in a microservices ecosystem. Implementation Adding Ribbon Dependency: To…

In this tutorial, we will start by understanding what is service discovery and then we will explore Netflix Eureka Server and Client setup, and finally the configuration in a sample Spring microservice project. Why Service Discovery? In a microservices architecture, each functionality is typically isolated into its separate service. These services then need…
