While protocol buffers and thrift have similar goals. Avro takes a different
approach to schema evolution and reconciliation. I feel that Avros tighter
layout of data and schema management is better suited for many of Hadoop and
Pigs use cases for large data sets/tables on HDFS. Field ids start to matter
when milions of objects have hundreds of fields each. There is, of course, the
storage overhead. Schema management becomes hard especially if there are cases
where field ids need to be assigned manually.
----- Original Message ---- From: Doug Cutting <cutt...@apache.org> To: gene...@hadoop.apache.org Sent: Thursday, April 2, 2009 3:05:08 PM Subject: [PROPOSAL] new subproject: Avro
I propose we add a new Hadoop subproject for Avro, a serialization system. My
ambition is for Avro to replace both Hadoop's RPC and to be used for most Hadoop
data files, e.g., by Pig, Hive, etc.
Initial committers would be Sharad Agarwal and me, both existing Hadoop
committers. We are the sole authors of this software to date.
The code is currently at:
http://people.apache.org/~cutting/avro.git/
To learn more:
git clone http://people.apache.org/~cutting/avro.git/ avro cat avro/README.txt
