Avro
Avro is a data serialization system that provides rich data structures and a compact, fast, binary data format. It is used for serializing data for communication between applications or systems.
Avro: Data Serialization System
Rich data structures and compact, fast, binary data format for serializing data in applications or systems
What is Avro?
Avro is an open source data serialization system developed within Apache's Hadoop project. It uses JSON for defining data types and protocols, and serializes data in a compact binary format.
Some key features of Avro include:
- Dynamic typing - no need to code up and compile data types ahead of time
- Untagged data - only the schema is required for interpreting data, reducing data size
- Language neutral - Avro data can be used by any language
- Rich data structures - supports arrays, maps, enumerations, fixed types, records
- Fast and compact serialization
- Container file format for managing large data sets
- Remote procedure call framework
Avro is widely used in big data applications both for data serialization and for defining interfaces between components. It strikes a nice balance between capabilities and complexity which makes it popular for big data file formats and message passing architectures.
