Hello! That *is* a more compelling use case for me, thanks for the clear
explanation.
So to summarize: permitting an "arbitrary POJO" as a JSON metadata (by
modifying {{JacksonUtils}}) will enable Avro reflection to better determine
default values in the generated schema for POJO.
That sounds alright for me!
I don't see backwards compatibility being a huge issue in this case for
developers relying on that exception being thrown for wrong data.
For my point #2 above (with {{Age}} going in, but {{Map}} coming out), maybe
it's enough to just have this clearly documented on the JsonProperties
interface. Or alternatively, only permit this behaviour when generating
defaults via ReflectData?

[~rskraba] My use case is: I want to extract default values for fields. Please
see my story here: [https://github.com/anhldbk/avro-fork]
For the time being, the code below throws exceptions:
{code:java}
import org.apache.avro.Schema;
import org.apache.avro.reflect.ReflectData;
public class AvroPlay {
public static class Age{
public int value = 9;
}
public static class Person{
public String name = "Andy";
public Age age = new Age();
}
public static void main(String[] args) {
ReflectData reflector = new ReflectData().setDefaultsGenerated(true);
Schema schema = reflector.getSchema(Person.class);
System.out.println(schema.toString(true));
}
}
{code}
When I run it, I've got an exception of:
{noformat}
Exception in thread "main" org.apache.avro.AvroRuntimeException: Unknown datum

org.apache.avro.util.internal.JacksonUtils.toJson(JacksonUtils.java:96)

So is it reasonable to modify the behavior of
`JacksonUtils.toJson(JacksonUtils.java:96)` a little bit?

Hello! Just a quick point of view on this -- if I understand correctly, the
goal is to be able to pass a POJO (that Jackson can handle) as a property
(metadata) value in a schema?
The code that would be exposed to the user would be something like this:
{code}
Schema s = ...
s.addProp("age", new Age(9));
...
// later
Map m = (Map) s.getObjectProp("age")
{code}
I don't see this being a great idea, as opposed to the current behaviour, which
is to only support a specified list of permitted java types, and throw an
exception otherwise.
My reasoning is:
# Turning a POJO into JSON is Jackson-specific behaviour and I'm not sure we
want to tie Avro behaviour to it. It might not be a big deal (if we're not
planning on replacing Jackson any time soon).
# Currently, what we put into a property value is also what we'll get out...
and I think will always be the expected behaviour for the user!
If we maintain the current behaviour, the user is responsible for turning the
POJO {{Age}} into the permitted java types, which seems reasonable to me.

Do you think our current tests are enough to validate compatibility? On our
mailing lists, I see so many concerns about backward compatibility. Do you
think we need to make breaking changes with Avro 2.x ?

Perhaps it's a non-issue. Today attempts to pass an arbitrary Java class to
this method would fail. An application could depend on this. So changing it
is marginally incompatible. Is it incompatible enough to worry about?

Doug Cutting commented on AVRO-2775:
The only downside I can see is that for applications that only intend to use
the types listed in
[JsonProperties|https://avro.apache.org/docs/current/api/java/org/apache/avro/JsonProperties.html],
changing this would permit them to include arbitrary Java data structures,
which might obscure a bug if this was not intended. Are there other
compatibility risks to adding this functionality?

I also think we should refactor JacksonUtils to clean it a little bit.
For example, currently we have:
{code:java}
public static Object toObject(JsonNode jsonNode, Schema schema) {
if (schema != null && schema.getType().equals(Schema.Type.UNION)) {
return toObject(jsonNode, schema.getTypes().get(0));
}
if (jsonNode == null) {
return null;
} else if (jsonNode.isNull()) {
return JsonProperties.NULL_VALUE;
} else if (jsonNode.isBoolean()) {
return jsonNode.asBoolean();
}
//. ..
}
{code}
We can have a better code the above:
{code:java}
public static Object toObject(JsonNode jsonNode, Schema schema) {
if (schema != null && schema.getType().equals(Schema.Type.UNION)) {
return toObject(jsonNode, schema.getTypes().get(0));
}
if (jsonNode == null) {
return null;
}
if (jsonNode.isNull()) {
return JsonProperties.NULL_VALUE;
}
if (jsonNode.isBoolean()) {
return jsonNode.asBoolean();
}
// ..
}
{code}
[~sekikn] do you think it's worth to refactor such code?

[jira] [Commented] (AVRO-2775) JacksonUtils: exception when calling toJsonNode()
[

Another problem is: currently JacksonUtils does NOT handle Short and Byte (see
[this
code|https://github.com/apache/avro/blob/master/lang/java/avro/src/main/java/org/apache/avro/util/internal/JacksonUtils.java#L82-L84]).
So I'm thinking of creating a PR to address them all.
[~fokko] [~sekikn] Please review my issue. Thank you!
