 Yes, each supports a JSON data encoding.  See
http://avro.apache.org/docs/1.3.3/spec.html#json_encoding for Avro and the
JSONProtocol in Thrift.  One clear advantage of these two is that they
support either stringified JSON or a compact binary encoding, and that they
each support (or intend to support) a more efficient TCP-based protocol
instead of only allowing HTTP.

Re: Avro vs Thrift, Cassandra has historically had difficulty getting Thrift
bugs fixed and Avro is more malleable at this point.  Additionally, Avro has
the potential for a more compact encoding and easier integration with
dynamic languages.
