Avro

Avro :

• Apache Avro is a language-neutral data serialization system. 
• Since Hadoop writable classes lack language portability, Avro becomes quite helpful, as it deals with data formats that can be processed by multiple languages. 
• Avro is a preferred tool to serialize data in Hadoop.
• Avro has a schema-based system. 
• A language-independent schema is associated with its read and write operations. 
• Avro serializes the data which has a built-in schema. 
• Avro serializes the data into a compact binary format, which can be deserialized by any application.
• Avro uses JSON format to declare the data structures. 
• Presently, it supports languages such as Java, C, C++, C#, Python, and Ruby.
