Spring Cloud Stream Applications Einstein SR5

Spring Cloud Stream Applications are standalone executable applications that communicate over messaging middleware such as Apache Kafka and RabbitMQ.

These applications can run independently on a variety of runtime platforms, including Kubernetes, Docker, Cloud Foundry, or even on your laptop.
Features

Out-of-the-box applications ready to run as standalone Spring Boot applications.

Assemble a set of applications into a coherent streaming data pipeline in Spring Cloud Data Flow.

Override configuration parameters via application properties, environment variables, or in the YAML file.

Quick Start

Step 1 - Download the latest time-source application from here [eg: /3.0.0.BUILD-SNAPSHOT/time-source-kafka-3.0.0.BUILD-SNAPSHOT.jar]

Step 2 - Download the latest log-sink application from here [eg: /3.0.0.BUILD-SNAPSHOT/log-sink-kafka-3.0.0.BUILD-SNAPSHOT.jar]

Step 3 - Start Kafka

Step 4 - Start the Time Source producer application pointing to ticktock topic in Kafka

java -jar time-source-kafka-***.jar --spring.cloud.stream.bindings.output.destination=ticktock

Step 5 - Start the Log Sink consumer application pointing to ticktock topic in Kafka

java -jar log-sink-kafka-***.jar --spring.cloud.stream.bindings.input.destination=ticktock

Step 6 - Verify ticktock output in the log-sink logs
