avro-explorations

This is a Java application written to illustrate the blog posts:

• You need two schemas to deserialize an Avro message… but which two? (dalelane.co.uk)
• You need two schemas to deserialize an Avro message… but which two? (community.ibm.com)

It produces messages to Kafka topics, serialized as binary-encoded Avro using a variety of Avro schemas.

It then consumes them, using different schemas to illustrate what happens if you don't use schemas correctly.

To build:

./0-compile.sh

Create a file called app.properties and add the config for your Kafka cluster to it.

To produce test messages:

./1-produce.sh

example output

To consume test messages and display the results:

./2-consume.sh

example output
