Apache Avro is a data serialization system.

Avro provides:

* Rich data structures.
* A compact, fast, binary data format.
* A container file, to store persistent data.
* Remote procedure call (RPC).
* Simple integration with dynamic languages. Code generation is not required
to read or write data files nor to use or implement RPC protocols. Code
generation as an optional optimization, only worth implementing for
statically typed languages.
