A protocol (and Python implementation) for RPC over ZeroMQ which uses JSON for data serialization. The resulting Python implementation is approx 5x faster than the corresponding xmlrpcserver & client in the single-threaded case, and nearly 10x faster in the multithreaded case. It is simple to achieve over 10K RPC calls/sec with this implementation.
- Python tested with 2.7
- ZeroMQ Python bindings
- UltraJson but you can plug in your own JSON serializer/deserializer
Create an instance of ZeroRpcServer, register functions and/or class instances, and call start(). Functions can be referenced by different names and/or organized into dotted namespaces.
def mult(a, b): return a * b server = zerorpc.server.ZeroRpcServer("tcp://*:5555") server.register_function(mult, name="my.namespace.mult") server.start(3, blocking=False)
Create an instance of ZeroRpcClient and call methods on it as if the functions were defined on that instance. The call is marshaled to the server transparently. Exceptions on the server are propagated to the client.
client = zerorpc.client.ZeroRpcClient("tcp://localhost:5555") result = client.my.namespace.mult(5, 7)
MultiCall works similarly to the xmlrpclib implementation. The calls are marshaled to the server, and the result is returned, in one network roundtrip.
client = zerorpc.client.ZeroRpcClient("tcp://localhost:5555") multicall = zerorpc.client.MultiCall(client) multicall.my.namespace.mult(2, 2) multicall.my.namespace.mult(3, 3) multicall.my.namespace.mult(4, 4) for result in multicall(): print result
