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.

prepare(*args, **kwargs)¶

static set_max_timeout(max_timeout)¶

Set RPC timeout ceiling for all backing-off RPC clients.
