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 containers + +`docker-compose down` + +of `docker-compose -f docker-compose-rabbit.yml down` if you are using the Rabbit binder. \ No newline at end of file diff --git a/schema-registry-samples/schema-registry-vanilla/consumer/.mvn b/schema-registry-samples/schema-registry-vanilla/consumer/.mvn new file mode 120000 index 0000000..71491fb --- /dev/null +++ b/schema-registry-samples/schema-registry-vanilla/consumer/.mvn @@ -0,0 +1 @@ +../../../.mvn \ No newline at end of file diff --git a/schema-registry-samples/schema-registry-vanilla/consumer/mvnw b/schema-registry-samples/schema-registry-vanilla/consumer/mvnw new file mode 100755 index 0000000..6efc7bd --- /dev/null +++ b/schema-registry-samples/schema-registry-vanilla/consumer/mvnw @@ -0,0 +1,226 @@ +#!/bin/sh +# ---------------------------------------------------------------------------- +# Licensed to the Apache Software Foundation (ASF) under one +# or more contributor license agreements.
