Summary: GenericDatumWriter Potential Performance improvement
Key: AVRO-3643
URL: https://issues.apache.org/jira/browse/AVRO-3643
Project: Apache Avro
Issue Type: Improvement
Components: java
Affects Versions: 1.11.1
Reporter: Paul Anderson
Attachments: image-2022-10-18-17-38-44-273.png
Sorry for the impetuous nature of this observation, however whilst trying to
resolve a Kafka client performance issue on Mainframe I noticed a potential
opportunity in Avro serialisation. I am using a compiled Avro schema and
noticed from my special profiling tool (see attached image) that
writeWithoutConversion calls resolveUnion which performs three HashMap.get's.
Seeing this a compiled serialiser is there not an opportunity to eliminate
these calls which would reduce the serialisation costs to the absolute minimum
.writeString (.writePrimitive).
