Avro Example Code
Does anyone have a good link or example code that we can use to spike on Avro with Cassandra?
Cheers.

Be warned: avro support is experimental and incomplete.
The avro system tests are probably the best place to start looking.

Fantastic! Thank you.

I've got a mostly working Avro server and client for HBase at
http://github.com/hammer/hbase-trunk-with-avro and
http://github.com/hammer/pyhbase. If you replace "scan" with "slice", it
shouldn't be too much different for Cassandra...

I spent the weekend working with avro and some java junit tests. I
still have a lot of learning to do, but if others would like to use,
add to or improve upon the tests then I would appricate the feedback
and help.

If you're using Python, the best place to look is the functional tests
(see test/system), otherwise, Patrick's quick start
(http://bit.ly/32T6Mk).
As Gary mentioned already, it's still very rough. After all the recent
changes in trunk (dropping the keyspace arg, binary keys, etc), it's
just barely back to a state where you can read/write, and only then via
get/insert (i.e. no slicing, batch_mutate, etc).

My Avro quickstart has an RPC example for various languages
