What is Apache Avro?
Avro is an open-source data serialization system that helps with data exchange between systems, programming languages, and processing frameworks. Avro helps define a binary format for your data, as well as map it to the programming language of your choice.
Avro has a JSON-like data model, but can be represented as either JSON or in a compact binary form. It comes with a very sophisticated schema description language that describes data. Avro is another Data Lake File Format.
