== Spring Schema Registry + Kafka Standalone
This sample application will demonstrate the combination of Spring's schema registry + Kafka + avro.
=== Running the application
- Start Kafka
[source,bash]
----
docker-compose up -d
----
- Start the Schema Registry server (Chnage these commands accordingly if you are not on a Unix like platform)
[source,bash]
----
wget -O /tmp/schema-registry-server.jar https://repo.maven.apache.org/maven2/org/springframework/cloud/spring-cloud-schema-registry-client/1.0.9.RELEASE//spring-cloud-schema-registry-server-1.0.9.RELEASE.jar
cd /tmp
----
Start the Schema Registry server using in-memory H2 database:
[source,bash]
----
java -jar schema-registry-server-1.0.9.RELEASE.jar
----
You might have to build this application to generate the avro classes.
For that, use the build command: `./mvnw clean package` (Or you can use your IDE plugins to generate the avro classes)
Then run this application.
You should see a one-time `Sensor` output from the consumer in the application (which is originally produced by the `CommandlineRunner`).
=== Cleanup
Once you are done with running the sample, stop the docker container.
`docker-compose down`
