摘要 在分布式数据库中,快照复制能够极大地提升系统性能。在使用快照复制的过程中,如果主表结构发生变化,则需要删除并重新创建快照,或者进行完全刷新,这将带来时间和资源的巨大消耗。作者在文中对此进行了深入分析,并提出了一种加速方法。 Snapshot replication can improve the performance rapidly. During this processing, if the structure of a master table has been changed, it will have to drop and recreate the snapshot or do a full refresh, which can be extremely time and resource consuming. This paper discusses this deeply, and offers a speedup method.
