== Spring Cloud Stream and Schema Evolution in Action with Kafka Binder.
|
||||
|
||||
These are a set of Spring Boot applications to demonstrate Schema Evolution using Spring Cloud Stream with Kafka 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
|
||||
For this demonstration, 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.
|
||||
|
||||
Both producers and consumers interact with the SCSt schema registry to register and evolve the schema.
|
||||
|
||||
[[build-apps]]
|
||||
=== Building the applications
|
||||
To build the applications simply execute the following command from the `scst-schema-registry-integration` directory:
|
||||
[source,bash]
|
||||
----
|
||||
./mvnw clean install
|
||||
----
|
||||
NOTE: The apps can be built and run from w/in an IDE (such as IntelliJ) but you will need to invoke the Maven `package` goal and then `refresh` the project as the Avro Maven plugin needs to execute so that it generates the required model classes - otherwise you will see compile failures around missing `Sensor` class.
|
||||
|
||||
[[run-apps]]
|
||||
=== Running the applications
|
||||
|
||||
==== Pre-requisites
|
||||
****
|
||||
* The components have all been built by following the <<build-apps>> steps.
|
||||
* Apache Kafka broker available at `localhost:9092`
|
||||
|
||||
By default, the schema registry is backed by an H2 database. If you want to instead use Postgres, it must be available at `localhost:5432`. Similarly, if you want to use MySQL it must be available at `localhost:3306`.
|
||||
|
||||
TIP: The included link:../../../tools/kafka/docker-compose/README.adoc#_all_the_things[Kafka tools] can be used to easily start a broker locally on the required coordinates
|
||||
****
|
||||
|
||||
==== Steps
|
||||
Make sure the above pre-requisites are satisfied and that you are in the `scst-schema-registry-integration` directory and follow the steps below.
|
||||
|
||||
- Start the Schema Registry server (Change these commands accordingly if you are not on a Unix like platform)
|
||||
[source,bash]
|
||||
----
|
||||
java -jar <ROOT-OF-SPRING-CLOUD-STREAM-CHECKOUT>/schema-registry/spring-cloud-stream-schema-registry-server-<VERSION>.jar
|
||||
----
|
||||
|
||||
This starts the schema registry with a local H2 database.
|
||||
|
||||
To use Postgres instead of H2, additional properties must be specified when starting the server:
|
||||
|
||||
[source,bash]
|
||||
----
|
||||
java -jar <ROOT-OF-SPRING-CLOUD-STREAM-CHECKOUT>/schema-registry/spring-cloud-stream-schema-registry-server-<VERSION>.jar \
|
||||
--spring.datasource.url=jdbc:postgresql://localhost:5432/registry \
|
||||
--spring.datasource.username=root \
|
||||
--spring.datasource.password=rootpw \
|
||||
--spring.datasource.driver-class-name=org.postgresql.Driver \
|
||||
--spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect \
|
||||
--spring.jpa.hibernate.ddl-auto-create=true \
|
||||
--spring.jpa.hibernate.ddl-auto=update \
|
||||
--spring.jpa.generate-ddl=true
|
||||
----
|
||||
|
||||
To use MySQL database instead of H2, additional properties must be specified when starting the server:
|
||||
|
||||
[source,bash]
|
||||
----
|
||||
java -jar <ROOT-OF-SPRING-CLOUD-STREAM-CHECKOUT>/schema-registry/spring-cloud-stream-schema-registry-server-<VERSION>.jar \
|
||||
--spring.datasource.url=jdbc:mariadb://localhost:3306/registry \
|
||||
--spring.datasource.username=root \
|
||||
--spring.datasource.password=rootpw \
|
||||
--spring.datasource.driver-class-name=org.mariadb.jdbc.Driver \
|
||||
--spring.jpa.database-platform=org.hibernate.dialect.MariaDB53Dialect \
|
||||
--spring.jpa.hibernate.ddl-auto-create=true \
|
||||
--spring.jpa.hibernate.ddl-auto=update \
|
||||
--spring.jpa.generate-ddl=true
|
||||
----
|
||||
|
||||
- Start `consumer` on another terminal session (or run it from an IDE)
|
||||
[source,bash]
|
||||
----
|
||||
java -jar scst-schema-registry-consumer-kafka/target/scst-schema-registry-consumer-kafka-<VERSION>-SNAPSHOT.jar
|
||||
----
|
||||
|
||||
- Start `producer1` on another terminal session (or run it from an IDE)
|
||||
[source,bash]
|
||||
----
|
||||
java -jar scst-schema-registry-producer1-kafka/target/scst-schema-registry-producer1-kafka-<VERSION>-SNAPSHOT.jar
|
||||
----
|
||||
- Start `producer2` on another terminal session (or run it from an IDE)
|
||||
[source,bash]
|
||||
----
|
||||
java -jar scst-schema-registry-producer2-kafka/target/scst-schema-registry-producer2-kafka-<VERSION>-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.
|
||||
|
||||
[source,bash,options=nowrap,subs=attributes]
|
||||
----
|
||||
{"id": "d135efc3-72f8-4612-9497-184cae508e31-v1", "internalTemperature": 34.36362, "externalTemperature": 0.0, "acceleration": 9.656547, "velocity": 33.29733}
|
||||
{"id": "3ecaae18-3144-4570-800a-223ca3198001-v1", "internalTemperature": 28.410656, "externalTemperature": 0.0, "acceleration": 1.752817, "velocity": 69.82016}
|
||||
{"id": "81262d85-2d60-40e8-9fcc-7f797fd6dcd4-v2", "internalTemperature": 11.2908125, "externalTemperature": 26.260101, "acceleration": 3.268205, "velocity": 3.331542}
|
||||
----
|
||||
|
||||
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.
