随着B4 C电子商务的高速发展，数据库渐渐成为瓶颈，很多B4 C电子商务系统都需要将现有数据库根据业务进行拆分，因此要考虑数据复制的问题。现有的系统一般采用读写分离来进行数据复制，数据复制粒度相对较粗，写操作容易成为瓶颈。使用流复制可以很方便地按照表或者表空间进行复制，并且支持双向复制，可以很容易地把现有系统扩展到多个数据库，从而提升系统的性能和扩展性。

With the fast development of B4C e-commerce, the database has gradually become a bottleneck of the businesses that use single database.Many B4C business systems need to split their databases based on business logic so data replication must be taken into consideration .Reading and writing are generally separated in data replication for current systems , the granularity of data replication is relatively coarse, and the writing operation tends to be a bottleneck .Streams replication makes it convenient to replicate data according to tables or tablespace , it also supports bi-directional replication , so that the current systems can be easily extended to multiple databases .These result in enhanced scalability and performance of the system .
