> A schema with a logicalType uuid field is incompatible with itself, per
> `SchemaCompatibility`:
>
> {code:java}
> use apache_avro::{Schema, schema_compatibility::SchemaCompatibility};
> fn main() {
> let schema_str = r#"\{"type": "string", "logicalType": "uuid"}"#;
> let writers_schema = Schema::parse_str(schema_str).unwrap();
> let readers_schema = Schema::parse_str(schema_str).unwrap();
> if let Err(err) = SchemaCompatibility::can_read(&writers_schema,
> &readers_schema) {
> eprintln!("Error: {}", err);
> }
> }
> {code}
>
> this is the behavior on `main` as of writing (`876eae32`) and on the latest
> version on crates.rs (`v0.16.0`)
> I have a proposed fix here:
> [https://github.com/apache/avro/compare/main...mknaw:avro:logical-type-compat-fix]
> Perhaps there are other valid logicalTypes with this behavior. I have not
> checked every logicalType yet.
