Description

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 https://github.com/apache/avro/pull/3168
