[rabbitmq-discuss] method-like calls

Hi

sorry for chiming in so late, last week we released our product (FluidDB)
after two years working on it.

What we did with Thrift and AMQP is to map this scenario [1] using Twisted, a
framework for asynchronous programming. The basic idea around txAMQP and
txThrift is to use a Deferred (a future/promise-like structure) to define
asynchronous calls to Thrift, and use AMQP as a transport.

Thrift is cross-language, so if you have a mixed environment, is worth having
a look. You don't need to use its RPC mechanism, you can just use it for
serializing/deserializing your objects and embed them in a Basic.Content
message. However, you'll have to build your own RPC mechanism in that case.

Cheers.
