Apache Kafka

Apache Kafka is an open-source stream-processing software platform developed by LinkedIn and donated to the Apache Software Foundation, written in Scala and Java. The project aims to provide a unified, high-throughput, low-latency platform for handling real-time data feeds, Kafka works well as a replacement for a more traditional message broker. This Project covers how to use Spring Boot with Spring Kafka to Publish JSON/String message to a Kafka topic

Start Zookeeper

• bin/zookeeper-server-start.sh config/zookeeper.properties

Start Kafka Server

• bin/kafka-server-start.sh config/server.properties

Create Kafka Topic

• bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic Kafka_Example

Consume from the Kafka Topic via Console

• bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic Kafka_Example --from-beginning

Publish message via WebService

• http://localhost:8080/kafka/trigger-object
• http://localhost:8080/kafka/trigger-string
