Doug Cutting commented on AVRO-1277: ------------------------------------ Re static caches: this should probably be addressed in a separate issue. > 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 > Attachments: AVRO-1277.patch, AVRO-1277-v2.patch > > > 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. -- This message is automatically generated by JIRA.
