anchor.diff:  === Converters with Schema Support
   
   The `AvroSchemaMessageConverter` supports serializing and deserializing messages either by using a predefined schema or by using the schema information available in the class (either reflectively or contained in the `SpecificRecord`).
  +If you provide a custom converter, then the default AvroSchemaMessageConverter bean is not created. The following example shows a custom converter:
  +
  +To use custom converters, you can simply add it to the application context, optionally specifying one or more `MimeTypes` with which to associate it.
  +The default `MimeType` is `application/avro`.
  +
   If the target type of the conversion is a `GenericRecord`, a schema must be set.

  == Schema Evolution Support
  
  Spring Cloud Stream provides support for schema-based message converters through its `spring-cloud-stream-schema` module.
  Currently, the only serialization format supported out of the box for schema-based message converters is Apache Avro, with more formats to be added in future versions.
  
  === Apache Avro Message Converters
  
  The `spring-cloud-stream-schema` module contains two types of message converters that can be used for Apache Avro serialization:
  
  * Converters that use the class information of the serialized or deserialized objects or a schema with a location known at startup.
