hello everyone,
thank you for such a wonderful project.
ufortunately there is no erlang implementation of avro so I have taken the
liberty to attempt such a task. as soon as I get something working I'll put
up the code, and if someone else is working on the same thing please let me
know - Im more than open to collaboration since my goal is to get and use a
working erlang avro lib.
Im reading the python implementation in details, as well as the 1.3
specification. the spec unfortunately is not clear (to me) in some parts so
I would like to ask the questions here and hopefully someone can provide
some clues/answers.
handshake request
its mentioned that a hash of the json protocol schema is sent on each
request to the server
{
"type": "record",
"name": "HandshakeRequest", "namespace":"org.apache.avro.ipc",
"fields": [
{"name": "clientHash",
"type": {"type": "fixed", "name": "MD5", "size": 16}},
{"name": "clientProtocol", "type": ["null", "string"]},
{"name": "serverHash", "type": "MD5"},
{"name": "meta", "type": ["null", {"type": "map", "values": "bytes"}]}
]
}
so the question is:
- both "clientHash" and "serverHash" should be replaced with the
actual hash of the protocol json definitions?
- what is the "server protocol"? if client and server are compatible
dont they both use the same protocol definition?
- the "type": ["null", "string"] syntax means that "type" key has
either "null" or "string" value?
