Avro

This article introduces Avro serialization

1 Introduction

Avro is a remote procedure call and data serialization framework developed within the Apache Hadoop project. It uses JSON to define data types and communication protocols, and a compact binary format to serialize data. It is primarily used with Hadoop, providing a serialization format for persistent data and serving as a protocol for communication between Hadoop nodes and from client programs to Hadoop services.
