Add rubygem-avro 1.8.2
This is the Ruby library of Apache Avro (devel/avro).
Apache Avro is a data serialization system which 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.
