Hey, So I've been playing with Avro the past few days through the Python bindings (thanks, Sharad!). I was able to get serialization and deserialization working in a reasonably hacky fashion when a file is only opened and written once (see http://github.com/hammer/avro-rpc-quickstart/blob/master/src/main/python/serialize_message.py ).
When I tried to serialize data to a file, close the file, and then open it up again, serialize another value, and close again, I am no longer able to read it back successfully (see http://github.com/hammer/avro-rpc-quickstart/blob/master/src/main/python/serialize_message.py.broken). I realize that the metadata gets written in the footer, and i tried to play around with sync() and seek() calls, but I wasn't able to figure out the correct mechanism. So: what's the proper way to crack open an existing file object container and append some additional values? I'd particularly appreciate a demonstration in Python. Thanks, Jeff
