--------------------------------------
I did some benchmarks for both the current implementation of serializing Avro records compared to this change, the results are located here:

> Automatically Use Avro Serialization for Avro Objects

> Key: SPARK-746
> URL: https://issues.apache.org/jira/browse/SPARK-746
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Reporter: Patrick Cogan
>
> All generated objects extend org.apache.avro.specific.SpecificRecordBase (or there may be a higher up class as well).
> Since Avro records aren't JavaSerializable by default people currently have to wrap their records. It would be good if we could use an implicit conversion to do this for them.
