The tacker.common.rpc Module

class tacker.common.rpc.BackingOffClient(transport, target, timeout=None, version_cap=None, serializer=None, retry=None)

Bases: oslo_messaging.rpc.client.RPCClient

An oslo messaging RPC Client that implements a timeout backoff.

This has all of the same interfaces as oslo_messaging.RPCClient but if the timeout parameter is not specified, the _ContextWrapper returned will track when call timeout exceptions occur and exponentially increase the timeout for the given call method.
