How to serialize java.math.BigDecimal in Avro?

Question

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

Answer 1

Avro introduced logical types in 1.7.7 (I believe) that should help you serialize decimal.

Answer 2

Here is the code :

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