Schema registry sample upgrade - Iteration 1
Convert the vanilla applications that uses the Spring provided Scheam registry and Avro message converters. Provide 2 sets of the same applications - one for the Kafka binder and another for the Rabbit binder. The top level folder of each of these sets are named appropriately so that anyone who is interested in a particular binder can easilty cd to that directory and run the samples

however, we will simply assume there are two producers producing events with different payload schemas. A consumer that

Both producers and consumers interact with this scheam registry to register and evolve the schema.

|

== Spring Cloud Stream and Schema Evolution in Action!
|
||||
|
||||
These are a set of Spring Boot applications to demonstrate Schema Evolution using Spring Cloud Stream with rabbit binder.
|
||||
Producer V1 (`producer1`), Producer V2 (`producer2`), and Consumer (`consumer`) are included in this project.
|
||||
|
||||
=== Requirement
|
||||
As a developer, I'd like to design my consumer to be resilient to differing payload schemas.
|
||||
|
||||
=== Assumptions
|
||||
There are a lot of online literature on Schema Evolution, so we are going to skip defining them here. For this demonstration,
|
||||
however, we will simply assume there are two producers producing events with different payload schemas. A consumer that
|
||||
consumes both the payload versions will be designed to adapt to evolving schemas.
|
||||
|
||||
=== Running the application
|
||||
|
||||
Make sure you are in the directory `schema-registry-vanilla-rabbit-binder`
|
||||
|
||||
Start rabbit
|
||||
|
||||
`docker-compose up -d`
|
||||
|
||||
Build the applications: `./mvnw clean package`
|

|

- 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.spring.io/libs-snapshot-local/org/springframework/cloud/spring-cloud-schema-registry-server/1.0.0.BUILD-SNAPSHOT/spring-cloud-schema-registry-server-1.0.0.BUILD-SNAPSHOT.jar
|
||||
cd /tmp
|
||||
java -jar schema-registry-server.jar
|

----
|
||||
- Start `consumer` on another terminal session (or run it from an IDE)
|
||||
[source,bash]

----
|

java -jar schema-registry-vanilla-consumer-rabbit/target/schema-registry-vanilla-consumer-rabbit-0.0.1-SNAPSHOT.jar

java -jar schema-registry-vanilla-producer1-rabbit/target/schema-registry-vanilla-producer1-rabbit-0.0.1-SNAPSHOT.jar

=== Sample Data
|
||||
Both the producers in the demonstration are _also_ REST controllers. We will hit the `/messages` endpoint on each producer
|
||||
to POST sample data.
|
||||
|
||||
_Example:_
|
||||
[source,bash]
|
||||
----
|
||||
curl -X POST http://localhost:9009/messages
|
||||
curl -X POST http://localhost:9010/messages
|
||||
curl -X POST http://localhost:9009/messages
|
||||
curl -X POST http://localhost:9009/messages
|
||||
curl -X POST http://localhost:9010/messages
|
||||
----
|
||||
|
||||
=== Output
|
||||
The consumer should log the results.
|
||||

||||

----
|
||||
|
||||
NOTE: Refer to the payload suffix in the `id` field. Each of them are appended with `-v1` or `-v2` indicating they are from
|
||||
`producer1` and `producer2` respectively.
|
||||
|
||||
=== What just happened?
|
||||
The schema evolved on the `temperature` field. That field is now split into `internalTemperature` and `externalTemperature`,
|
||||
as two separate fields. The `producer1` produces payload only with `temperature` and on the other hand, `producer2` produces
|
||||
payload with `internalTemperature` and `externalTemperature` fields in it.
|
||||
|
||||
The `consumer` is coded against a base schema that include the split fields.
|
||||
|
||||
The `consumer` app can happily deserialize the payload with `internalTemperature` and `externalTemperature` fields. However, when
|
||||
a `producer1` payload arrives (which includes `temperature` field), the schema evolution and compatibility check are automatically
|
||||
applied.
|
||||
|
||||
Because each payload also includes the payload version in the header, Spring Cloud Stream with the help of Schema
|
||||
Registry server and Avro, the schema evolution occurs behind the scenes. The automatic mapping of `temperature` to
|
||||
`internalTemperature` field is applied, since that's the field where the `aliases` is defined in the link:https://github.com/sabbyanandan/schema/blob/master/consumer/src/main/resources/avro/sensor.avsc#L7[new schema].
|
||||
|
||||
=== Cleanup
|
||||
|
||||
Once you are done with running the samples, stop the docker container
|
||||
|
||||
`docker-compose down`
