----------------------------------

             Summary: Improve performance of reflection-based serializers
                 Key: AVRO-1277
                 URL: https://issues.apache.org/jira/browse/AVRO-1277
             Project: Avro
          Issue Type: Improvement
          Components: java
    Affects Versions: 1.7.4
            Reporter: Leo Romanoff
            Priority: Minor


I've played a bit with Avro serialization based on reflection, i.e. with the classes from
org.apache.avro.generic package.

It works fine in this mode, but is rather slow compared to such frameworks like protostuff
or kryo.

Quick look at the source code has shown that a lot of reflection-based operations and class
lookups are not cached. And such operations are usually pretty expensive when executed by
a JVM. 

So I changed some of org.apache.avro.generic classes, introduced caching and a few other optimizations.
Now it seems to perform much better.
