Introduction

A distributed event-driven microservices project using Spring boot, Spring cloud, Kafka and Elasticsearch

• Implemented CQRS and event sourcing pattern in Spring Boot, Spring Cloud, Apache Kafka, and Elasticsearch
• Utilized mock streaming tweets as source data and Docker for microservices containerization
• Adopted accept header/ content negotiation pattern for API versioning
• Externalized configuration in a separate config server repository

Event-driven Microservices Architecture

Live Demo

• Containerization of three microservices with docker images:
  • twitter-to-kafka-service
  • kafka-to-elastic-service
  • elastic-query-service
