Instance Constructors

new PaxosActorNoTimeout(config: PaxosProperties, nodeUniqueId: Int, journal: Journal)

config
Configuration such as timeout durations.
nodeUniqueId

journal
The durable journal required to store the state of the node in a stable manner between crashes.

def send(actor: ActorRef, msg: Any): Unit

If you require transactions in the host application then you need to supply a custom Journal which participates in your transactions.
If you require transactions in the host application then you need to supply a custom Journal which participates in your transactions. You also need to override this method to buffer the messages then either send them post commit else delete them post rollback. Paxos is safe to lost messages so it is safe to crash after committing the journal before having sent out the messages. Paxos is *not* safe to "forgotten outcomes" so it is never safe to send messages when you rolled back your custom Journal.
