> Improve encode/decode time for SpecificRecord using code generation
> -------------------------------------------------------------------
>
> Key: AVRO-2090
> URL: https://issues.apache.org/jira/browse/AVRO-2090
> Project: Avro
> Issue Type: Improvement
> Components: java
> Reporter: Raymie Stata
> Assignee: Raymie Stata
> Attachments: customcoders.md
>
>
> Compared to GenericRecords, SpecificRecords offer type-safety plus the
> performance of traditional getters/setters/instance variables. But these are
> only beneficial to Java code accessing those records. SpecificRecords
> inherit serialization and deserialization code from GenericRecords, which is
> dynamic and thus slow (in fact, benchmarks show that serialization and
> deserialization is _slower_ for SpecificRecord than for GenericRecord).
> This patch extends record.vm to generate custom, higher-performance encoder
> and decoder functions for SpecificRecords. We've run a public benchmark
> showing that the new code reduces serialization time by 2/3 and
> deserialization time by close to 50%.
