When a system becomes partitioned, there are two possibilities. The system can shut off activity and wait for the connection8 to be reestablished, or it can adjust its behavior and attempt to continue running. Since a major goal of distributed systems is to be resilient in the face of failures, the first alternative is clearly undesirable. “his paper explores approaches to the second alternative.","PeriodicalId":255063,"journal":{"name":"Adv.
