-----------------------------------------------
> [Rust] Faster is_nullable for UnionSchema
> -----------------------------------------
>
> Key: AVRO-4007
> URL: https://issues.apache.org/jira/browse/AVRO-4007
> Project: Apache Avro
> Issue Type: Improvement
> Components: rust
> Reporter: Martin Tzvetanov Grigorov
> Assignee: Martin Tzvetanov Grigorov
> Priority: Minor
>
> https://github.com/apache/avro/pull/2961
> {code}
> Writing large amounts of avro data in rust is slow because (in my case) ~40%
> of total run time is spent in the function UnionSchema::is_nullable. The
> issue is that the x == Schema::Null invokes schema canonicalization which is
> apparently somewhat slow. I've modified the method to use match instead and
> see a considerable performance improvement.
