Martin Traverso commented on AVRO-143:
--------------------------------------
I did something similar a while ago for Thrift: http://github.com/martint/swift
Essentially, it takes a schema and a class representing a java bean or a Map
and it generates a class dynamically that knows how to call the right methods
as it reads and writes raw fields from the underlying transport.
I wouldn't expect porting it to work with Avro to be too complicated, and I've
been thinking about doing it at some point.
> use ASM to accellerate reflection

> Key: AVRO-143
> URL: https://issues.apache.org/jira/browse/AVRO-143
> Project: Avro
> Issue Type: Improvement
> Components: java
> Reporter: Doug Cutting
>
> Java reflection is very slow, about 100 times slower for field access than
> normal Java code. However reflection might be a useful tool for converting
> existing codebases to use Avro.
> One could, using ASM (http://asm.ow2.org/) make existing compiled classes to
> implement the SpecificRecord interface or something similar:
> http://hadoop.apache.org/avro/docs/current/api/java/org/apache/avro/specific/SpecificRecord.html
> This would make existing classes as fast to serialize as generated classes.
