Overview: In this tutorial, I would like to show you a simple implementation of Choreography Saga Pattern with Spring Boot. Over the years, Microservices have become very popular. Microservices are distributed systems. They are smaller, modular, easy to deploy and scale etc. Developing a single Microservice application might be interesting! But handling a business transaction […]
Overview In this tutorial, I would like to demo Circuit Breaker Pattern, one of the Microservice Design Patterns for designing highly resilient Microservices using a library called resilience4j along with Spring Boot. This article assumes you are familiar with Retry Pattern – Microservice Design Patterns. Need For Resiliency Microservices are distributed in nature. When you work with distributed systems, always remember
Overview In this tutorial, I would like to demo Bulkhead Pattern, one of the Microservice Design Patterns for designing highly resilient Microservices using a library resilience4j along with Spring Boot. Need For Resiliency Microservices are distributed in nature. When you work with distributed systems, always remember this number one rule – anything could happen. We might be dealing with network issues,
Overview: In this tutorial, Let’s develop a simple application to demonstrate Spring WebFlux Aggregation (aka Gateway Aggregation) to send requests to multiple Microservices and gather responses from them to aggregate into a single response. Spring WebFlux Aggregation: In a Microservice architecture, we will have N number of services and each service has its own responsibilities
Overview: In this tutorial, I would like to show you Spring WebFlux WebSocket to enable a real-time communication between a client and the server. Spring WebFlux WebSocket: Spring WebFlux is a non-blocking web stack to handle multiple concurrent requests with minimal number of threads and scale with fewer hardware resources. WebSocket is a standardized way
Overview: In this tutorial, I would like to show you a simple implementation of Orchestration Saga Pattern with Spring Boot. Over the years, Microservices have become very popular. Microservices are distributed systems. They are smaller, modular, easy to deploy and scale etc. Developing a single Microservice application might be interesting! But handling a business transaction which
Overview: In this tutorial, Let’s build a simple application to stream video files with Spring WebFlux Video Streaming. It is going to be a lot simpler than you think as Spring does all the heavy lifting for us. (You do not have to serve the static content as shown in this post. It is a
Overview: In this article, I would like to show Redis PubSub with Spring Boot which can be used to broadcast messages across multiple services in a Microservices architecture. I assume you have basic knowledge on Redis + Spring Boot integration. If you are new to Spring Boot Redis, check the below article. Spring WebFlux Redis
Overview: In this tutorial, I would like to show you how we can use Spring WebClient with Feign to make HTTP calls in reactive manner. Spring WebClient with Feign: Spring WebClient is a non-blocking reactive client to make HTTP requests. Feign is a library which helps us to create declarative REST clients easily with annotations and
Overview: In this tutorial, I would like to show you the R2DBC Query By Example API with Spring WebFlux and how we can use this to search for records without exposing multiple methods in our Repository object. Lets first see what it is exactly before diving into coding. Query By Example: Query By Example (QBE)
