> I'm going to speak about Rust implementation(crate) of Avro named "apache-avro"([crates.io|[https://crates.io/crates/apache-avro]).]
> Currently, union resolving is implemented as "iterate through listed schemas and find the first that matches given value". Process of finding requires schemas validation against that value. Validation method contains single "error!" macro invocation.
> So, even if union contains relevant schema as variant, previous bad matches would throw error! log macro. In result, with big unions, you get a flooded logs.
> My proposition is to write separate "validate" method that won't invoke error! macro and use it during union resolution.
> UPD: It seems that problem only occurs when complex types are included in union schema, see example in comments.
