Put data points over HTTP

Put data points over HTTP

vote for the last option. I don't think JSON is necessary for TSD because data points does not contain any internal structure currently.

How would we communicate failures/warnings back to the client? This something that I struggle with the current RPC calls too.

The current "RPC" calls are just a dumb, telnet-style protocol. It's not a real RPC protocol. I looked at Thrift but no implementation was suitable for me. I looked at MessagePack too but the code was undocumented and the implementation wasn't suitable either. I've been considering to implement a proper RPC service with Protocol Buffers but haven't had time to do so.

The telnet-style protocol doesn't allow you to handle errors when putting data points. HTTP wouldn't allow you to handle errors either, unless you send data points one by one (unacceptable performance-wise) or unless you use something like JSON-RPC.

@tsuna, for starters I would go with something that conveys "all good" v/s "one or more of your requests could not be processed". The details can follow as arbitrary unstructured text just the way it does if we were to do an import from the command line.

I'm working on the JSON formatted ingest, see google groups
