Tx

trait Tx[+T] extends AnyRef

A Tx is used to mediate multi-party transactions with the following protocol:

  1. A transaction is complete when all parties have completed acknowledgment. 2. If any party aborts (nack), the entire transaction is considered aborted. 3. Once a transaction has been acknowledged by a party, that acknowledgment must be honored: The party cannot subsequently nack.
