-------------------------------------------------------------------
It is not necessarily a bug. The specification explains that Array _"[support a
single attribute|https://avro.apache.org/docs/1.12.0/specification/#arrays]"._
But the example exposes an unspecified {{_default_}} field.
[~mgrigorov], the specification should be clarified first. It is the same thing
for Maps

> While trying to write an Iceberg Manifest List File, which is essentially an
> Avro File with some custom attributes I ran into a few issues which to the
> best of my knowledge are not present in other language implementations or the
> Avro spec. So far I have encountered these issues with the C++ library
> * Arrays are not capable of having custom attributes
> * Attributes in general have to be strings or null. I.e. integers are not
> supported
> I am willing to address these issues myself by writing PRs for the individual
> issues (at least for the first one I know how to fix it. Please let me know
> if there are already any efforts to fix this or reasons why the encountered
> behavior should be preserved.
>
> Edit: PR for custom attributes in arrays exists already
