Since those triggered actions are typically one or more insert, UPDATE, or DELETE statements, the overhead of triggers can be substantial in a mass insert operation.

由于那些被触发的动作通常是一条或多条insert、UPDATE或delete语句，因此，在数据量很大的insert中，触发器的开销会很大。

In a similar manner, you can break up mass UPDATE, DELETE or INSERT operations into separate jobs.

按照类似的方式，您可以将mass UPDATE、DELETE或INSERT操作拆成多个不同的任务。

Once found, a process that could take up to six months, researchers will insert the genes into bacteria that are genetically engineered to mass-produce enzymes for even finer testing.

一旦一种新的菌类基因被发现，则需要一个大约6个月的程序，研究者们会把基因植入培养菌，那是从基因工程方面大量生产酶，以便于更加深入的实验。
