rstata commented on issue #256: AVRO-2090: Improve encode/decode time for
SpecificRecord using code generation
URL: https://github.com/apache/avro/pull/256#issuecomment-425690934
I will update this patch. The old changes were easily rebased onto Avro's
current master. You can see that result here:
https://github.com/rstata-projects/avro/tree/specific-new-rebased
I then started addressing the comments above. I just closed a few of the
change requests from above -- you can find the resulting changes here:
https://github.com/rstata-projects/avro/tree/AVRO-2090-again
I'll keep working on this over the next few days. In the meantime, if folks
have applications that use SpecificRecord, it'd be great if you could enable
this feature and run it through your test cases.

> 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
> Priority: Major
> 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%.
