> Ruby: Unnecessary memory allocations during serialization
> ---------------------------------------------------------
>
> 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.
