Hi, I’m fairly new to working with avro so I could be wrong however this:
https://avro.apache.org/docs/1.7.7/api/java/org/apache/avro/SchemaBuilder.html “Primitive Types All Avro primitive types are trivial to configure. A primitive type in Avro JSON can be declared two ways, one that supports custom properties and one that does not: {"type":"int"} {"type":{"name":"int"}} {"type":{"name":"int", "customProp":"val"}} The analogous code form for the above three JSON lines are the below three lines: .intType() .intBuilder().endInt() .intBuilder().prop("customProp", "val").endInt() Every primitive type has a shortcut to create the trivial type, and a builder when custom properties are required. The first line above is a shortcut for the second, analogous to the JSON case.” makes it look like you can.
