>                 Key: AVRO-2984
>                 URL: https://issues.apache.org/jira/browse/AVRO-2984
>             Project: Apache Avro
>          Issue Type: Improvement
>          Components: ruby
>    Affects Versions: 1.10.0
>            Reporter: Joel Turkel
>            Priority: Major
>
> Profiling our Ruby event publishing pipeline, we see two big sources of unnecessary memory allocations:
>  # Avro::IO:DatumWriter#write_data allocates a hash of constant validation options
>  # Avro::SchemaValidator::Result allocates an errors array which is unnecessary for the common case of no validation errors
> This is on a very hot codepath for us and accounts for roughly 30% of the memory allocated by this part of the event publishing pipeline.
> Github PR coming shortly.
