Java Microservices Kafka POC

This repository demonstrates a Proof-of-Concept (POC) microservices architecture using Apache Kafka as the backbone for asynchronous communication between services. The project leverages Spring Boot for rapid microservice development, integrates with Cassandra for data storage, and uses RestTemplate for synchronous HTTP interactions.

Features

• Microservices communication via Apache Kafka
• Built with Spring Boot
• Data persistence with Cassandra
• RESTful endpoints using RestTemplate

Technologies Used

• Java
• Spring Boot
• Apache Kafka
• Cassandra
• RestTemplate

Getting Started

Prerequisites

• Java (JDK 8 or higher)
• Apache Kafka
• Cassandra
• Maven

Setup & Installation

1. Clone the repository:

   git clone https://github.com/Saurabhsds13/java-microservices-kafka.git
   cd java-microservices-kafka

2. Configure Kafka and Cassandra as per your environment.

3. Build the project:

   mvn clean install

4. Start each microservice (replace <service-directory> with actual service directories):

   cd <service-directory>
   mvn spring-boot:run

Running the Project Locally

• Ensure Kafka and Cassandra are running.
• Start all microservices as described above.
• Each service exposes REST endpoints; you can interact with them using tools like Postman or curl.

Example Usage

• Microservices communicate asynchronously via Kafka topics.
• Synchronous REST calls are made using RestTemplate.
• Data is persisted in Cassandra.

This project is a personal POC and is not currently accepting external contributions.
