Abstract: In general, the subject matter described in this disclosure can be embodied in methods, systems, and program products. A computing system receives a first request to insert one or more first data values into a database table. The computing system identifies that first data stored by the database table is stored in a first logical partition of a logical collection of data. The logical collection of data is designated for replication among multiple data centers such that a copy of the logical collection of data is designated to be stored by each of the multiple data centers. The logical collection of data is logically partitioned into multiple logical partitions which together comprise the logical collection of data. The computing system sends, by the computing system and to the first data center, the first request to insert the one or more first data values into the database table.

Abstract translation: 通常，本公开中描述的主题可以体现在方法，系统和程序产品中。 计算系统接收将一个或多个第一数据值插入到数据库表中的第一请求。 计算系统识别由数​​据库表存储的第一数据被存储在数据的逻辑集合的第一逻辑分区中。 指定数据的逻辑集合用于在多个数据中心之间进行复制，使得数据的逻辑集合的副本被指定为由多个数据中心中的每一个存储。 数据的逻辑集合在逻辑上被分割成多个逻辑分区，它们一起构成数据的逻辑集合。 计算系统由计算系统和第一数据中心发送将一个或多个第一数据值插入到数据库表中的第一请求。
