  -== Using the Avro data format
  -
  -Using the avro data format is as easy as specifying that the class that
  -you want to marshal or unmarshal in your route.

  -[source,xml]
  ---------------------------------------------------------------------------------
  -    <camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
  -        <route>
  -            <from uri="direct:in"/>
  -            <marshal>
  -                <avro instanceClass="org.apache.camel.dataformat.avro.Message"/>
  -            </marshal>
  -            <to uri="log:out"/>
  -        </route>
  -    </camelContext>

  -An alternative can be to specify the dataformat inside the context and
  -reference it from your route.

  -        </dataFormats>
  -        <route>
  -            <from uri="direct:in"/>
  -            <marshal><custom ref="avro"/></marshal>
  -            <to uri="log:out"/>
  -        </route>

  -In the same manner you can umarshal using the avro data format.

   == Using Avro RPC in Camel
   
   As mentioned above Avro also provides RPC support over multiple

  == Avro RPC Headers
  
  [width="100%",cols="20%,80%",options="header",]
  
negative.code: | *configuration* (advanced) | To use a shared AvroConfiguration to configure options once |  | AvroConfiguration

  // component options: END
  
  // endpoint options: START
  The Avro endpoint is configured using URI syntax:
