**Since Camel 2.14**
This component provides a dataformat for avro, which allows
serialization and deserialization of messages using Apache Avro’s binary
dataformat. Since Camel 3.2 rpc functionality was moved into separate
`camel-avro-rpc` component.
There is also `camel-jackson-avro` which is a more powerful Camel
dataformat for using Avro.
Maven users will need to add the following dependency to their `pom.xml`
for this component:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-avro</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>
You can easily generate classes from a schema, using maven, ant etc.
More details can be found at the [Apache Avro
documentation](http://avro.apache.org/docs/current/).
# Avro Dataformat Options
# Examples
## Avro Data Format usage
Using the avro data format is as easy as specifying that the class that
you want to marshal or unmarshal in your route.
AvroDataFormat format = new AvroDataFormat(Value.SCHEMA$);
from("direct:in").marshal(format).to("direct:marshal");
from("direct:back").unmarshal(format).to("direct:unmarshal");
Where Value is an Avro Maven Plugin Generated class.
or in 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" library="ApacheAvro"/>
</marshal>
<to uri="log:out"/>
</route>
</camelContext>
An alternative can be to specify the dataformat inside the context and
reference it from your route.
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<dataFormats>
<avro id="avro" instanceClass="org.apache.camel.dataformat.avro.Message" library="ApacheAvro"/>
</dataFormats>
<route>
<from uri="direct:in"/>
<marshal><custom ref="avro"/></marshal>
<to uri="log:out"/>
</route>
</camelContext>
In the same manner, you can unmarshal using the avro data format.
