In my case, I'd like the database to have a clean set of data before each logical test collection is run.
在本文的示例中,在运行每个逻辑测试集合前,我希望数据库具有一组干净的数据。
This is why there is less overhead for dirty data as compared to clean data.
这就是与干净数据相比,“脏数据” 的开销更小的原因所在。
However, when data is not clean, the duplicate records get dropped and there is less data to load into the database. This reduces loading time.
但是,当数据不干净时,副本记录将被弃用,只需将较少的数据加载到数据库,这将减少加载时间。
