@Eric I agree with many of your sentiments.

The "avro summary" was/is somewhere between wishful thinking and
educated guesswork. In ~ May 2010 a shiny new Avro project went top
level apache status. Meanwhile thrift had no full time committers and
had some glaring bugs that had been open in thrift 0.4.0 (some around
php) that annoyed everyone.

However thrift did have a release 0.5.0. There are some projects that
use thrift, Hbase, Cassandra, and Hive. Thrift still delivers on
bindings for a number of languages.

Avro is in catchup mode to thrift. They are still evolving the
project, while still trying to add support for more languages. As far
as I can tell there is no flagship project build around Avro

It would be a shame to see the Avro support go away from Cassandra
because of all the hard work that was put into it. However the
maintenance cost might outweigh it's benefits.
