Optiminzing 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.
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.
