appendix C Working with Avro, Protobuf, and JSON Schema
C.1 Apache Avro
An Avro schema is composed of two main types: primitive and complex. The supported primitive types are null, boolean, int, long, float, double, bytes, and string. Complex types are records, enums, arrays, maps, unions, and fixed. For a complete description of primitive and complex types, see the Avro documentation at http://mng.bz/Y7Oo and http://mng.bz/GZ2M, respectively.
In this book, you’ll mostly work with the complex type of record as this corresponds to an object. You may also encounter a few examples using primitive values, but for the most part, we’ll stick with records. You’ll also use the union type, especially when working with the RecordNameStrategy
