Mysql MongoDB的意思|示意

MongoDB provides replication features in a master-slave configuration (similar to MySQL) for the purposes of failover and redundancy, ensuring a high level of consistency between nodes.

为了实现故障转移和冗余，MongoDB在主从配置中提供了复制特性(类似于MySQL)，从而确保节点之间的高度一致性。

PostgreSQL is an interesting addition since it is a full featured traditional database with a different audience than MySQL or MongoDB users.

将PostgreSQL纳入CloudFoundry还是很有趣的，因为它是一个非常有特色的传统数据库，其受众较之mysql或MongoDB的用户截然不同。
