Abstract

A partitioning of a distributed database! system (DDBS) occurs when the DDBS is djvided into two or more subsets such that no member of one subset can communicate with any member of another. 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.

提高分区数据库系统中的可用性
一个分布式数据库的分区!当DDBS被划分为两个或多个子集,使得一个子集的任何成员都不能与另一个子集的任何成员通信时,就会出现这种情况。当系统被分区时,有两种可能。系统可以关闭活动并等待连接重新建立,也可以调整其行为并尝试继续运行。由于分布式系统的主要目标是在面对故障时保持弹性,因此第一种选择显然是不可取的。他的论文探讨了第二种选择的方法。
