Review Comment:
nit: as mentioned on https://github.com/apache/iceberg/pull/5893 I still
think this should use the enums from `AvroCodec` as it's not clear that those
are actually avro codecs. I'm curious what others think here

Review Comment:
this is what's causing the RevAPI breaks. I think it would be better to have
```
protected FileAppender<ManifestFile> newAppender(
OutputFile file,
Map<String, String> meta,
String compressionCodec,
Integer compressionLevel) {
return newAppender(file, meta, null, null);
}
```
which calls the original `newAppender(..)` method with either nulls or
default values for compression codec & level

looks like there's a newer version available

we switch to that?

Review Comment:
rather than having to break the API I think it would be better to define a
new `newAppender(..)` method that by default calls the original one with
null/default params. See also my comment further below.
Once this is done, you shouldn't have any diff on `revapi.yml` anymore.

Review Comment:
agreed, there doesn't seem too much value in having this in a constant field
