> Optimizing ResolvingDecoder for default values
> ----------------------------------------------
>
> Key: AVRO-383
> URL: https://issues.apache.org/jira/browse/AVRO-383
> Project: Avro
> Issue Type: Improvement
> Components: java
> Reporter: Thiruvalluvan M. G.
> Assignee: Thiruvalluvan M. G.
> Attachments: AVRO-383-new-test.patch, AVRO-383-new.patch,

>
> When the reader's and writer's schemas are records and the reader's schema
> has a field with default value and the writer's schema doesn't have the
> field, the ResolvingDecoder keeps the default value in a byte array. This
> byte array is in Json format. Moving this to Avro binary format improves
> performance.
> Apply the test patch and try "Perf -M". Then apply the patch and run it
> again. On my machine, the performance is three times the original.
