Hi Steve,
I'm seeing the same issue. I think you'll need to drop down to JSON. The
IDL appears to provide a subset of the Avro specification.
I've started mapping the gaps with the following record type:
enum YesNo { YES, NO }
fixed TWO(2);
record IdlHarness {
// primitives
boolean bool = true;
int i = 0;
int iN = null;
long l = 0;
long lN = null;
float f = 0.1;
float fN = 0.1;
double d = 0.1;
double dN = null;
bytes b = "banana";
bytes bN = null;
string s = "s";
string sN = null;
// complex
YesNo en = "YES";
YesNo enN = null;
array<int> a = [1];
array<int> aN = null;
map<int> m = { "hello": 1 };
map<int> mN = null;
union {null, string} un = "hello";
union {null, string} unN = null;
TWO fix = "12";
TWO fixN = null;
// logical
// decimal dec; // error
date dt = "2017-01-01";
date dtN = null;
// time-millis ms; // fails
// time-micros us; // fails
// timestamp-millis tsms; // fails
// timestamp-micros tsus; // fails
// duration du; // fails
}
I've put my results into the Google sheet below. It's still a work in
progress and I'll try to turn it into a JUnit test scenario.

Kind regards,

Hi Avro users mailing list,
I'm having trouble writing an Avro schema for java.math.BigDecimal type, I
tried the following:
1. Based on Avro official doc:
https://avro.apache.org/docs/1.8.1/spec.html#Decimal, I know I need to
define Logical Types myself to support BigDecimal, but that link gives
example only in avsc, I'm trying to figure it out in avdl.
2. Based on Avro dochttps://
avro.apache.org/docs/1.7.6/api/java/org/apache/avro/reflect/package-summary.html
and this example:
https://github.com/apache/avro/blob/master/share/test/schemas/stringables.avdl,
I wrote below avdl:
@namespace("test")
protocol My_Protocol_v1 {
record BigDecimal {
@java-class("java.math.BigDecimal") string value;
}
But it's not working:
This IDL schema compiles fine and can generate a Java class called
BigDecimal, but I cannot really use the generated BigDecimal as
java.math.BigDecimal, what's wrong? or How should I do it?
Thanks a lot
Steve
