How to serialize java.math.BigDecimal in Avro?

Question

Avro schemas are defined using JSON. Schemes consist of primitive types (null, boolean, int, long, float, double, bytes and string) and complex types (record, enumeration, array, map, union and fixed). I want to ask which one is suitable for BigDecimal.

Answer 1

Avro introduces boolean types in 1.7.7 (I believe), which should help you serialize decimal numbers.

Answer 2

Here is the code:

"type": [ {
    "type": "string",
    "java-class": "java.math.BigDecimal"
 } ]
