When there are no dependent materialized query tables (MQT), the system initiates the second phase after the first phase (ALTER table DETACH PARTITION) commits.
当不存在依赖的物化查询表(MQT)时,系统在完成第一阶段(ALTERTABLEDETACHPARTITION)的提交后,启动第二阶段。
What happens during the partition migration phase?
在分区转移阶段会发生什么?
Because ObjectGrid only supports single-phase commit transactions, any update can only be performed in a single partition.
由于ObjectGrid只支持单阶段提交事务,因此任何更新都只能在单个分区内执行。
This is because the ObjectGrid only supports one-phase commit transactions (which are much faster than two-phase commit) and therefore a query can only span a single partition.
这是因为ObjectGrid只支持单阶段提交事务(比两阶段提交要快得多),因此一次查询只能跨越单个分区。
Oil-water partition coefficient of MD-1 was far less than 1, which revealed its less solution in oil phase.
MD1膜驱剂的油水分配系数远小于1,说明其在油相中的溶解量很小。
The sorption of acenaphthene and phenanthrene was characterized by linear isotherm indicating solute partition between water and the organic phase in soil.
土壤对多环芳烃的吸附去除效果明显,其中苊和菲的吸附等温线呈线性。
When the stationary phase is a liquid or a solution partition mechanism governs the retention of reversed-phase paper chromatography just as in liquid-liquid extraction.
本文认为当固定相为液体或溶液时,反相纸层析与液液萃取一样属于分配机制。
A new delay partition method is also adopted to improve the speed of the post-scale counter, which is used to realize the programmable phase shift and duty cycle.
本文还提出了一种延时分割方法以提高用于实现相移和占空比调节功能的后端分频器的速度。
