This method discards modifications to data since the last save or load operation if both of the following conditions are met 如果满足下面的两个条件,此方法将会丢弃自上次保存或加载操作之后对数据的修改:
That means an etl extract , transform , and load operation that normally takes an hour could take a full day to profile 这意味着正常情况下只需要一小时的一个efl (提取、转换、装入)操作,可能要花一整天才能监测!
For example , db2 load could run simultaneously on each partition , splitting the load operation up in parallel across the servers 例如, db2 load可以在每个分区上同时运行,负载操作可以并行地分摊到多个服务器上。
You may also want to consider using dpf if you are doing extract , transform , and load operations and your batch window is small 如果要处理提取、转换和载入操作( etl ) ,而批处理窗口又比较小,那么可以考虑使用dpf 。
Manages project persistence and stores and retrieves code and other items using save and load operations implemented by the host 对项目持久性进行管理,并对使用由宿主实现的保存和加载操作的代码和其他项进行存储和检索。
Specifies that a bulk update table - level lock is acquired for the duration of the bulk load operation ; otherwise , a row - level lock is acquired 指定在大容量加载操作期间获取大容量更新表级别的锁;否则,获取行级别的锁。
The purpose of load demand controls is to reduce fuel consumption and limit problems caused by light load operation of reciprocating diesel generator sets 负载需求控制的目的是降低燃料的消耗量,减少往复式柴油发电机组因低负荷造成的故障。
Rigidity and reliable - - - - - - loading operation continually , and there just need the minimum maintain , the air balance offer the better capability of the cost benefit 坚固可靠? ?连续负载运行,只需最少量维护保养,平衡空气提供成本效益优良的性能。
The thesis is based on automatic loading system . at first it introduces the traditional performance in this field , then it has designed a new scheme with studing practical loading operation 本文以实际的集装箱自动装载系统为研究背景,设计出一种三层逐次优化的装箱方案。
