还可以修改表的大小(每个页面上的条目数量)和数据刷新频率以满足自己的需要。
The size of the table (number of entries per page) and data refresh rates can also be changed to meet the your needs.
根据表中数据发生改变的速度,调整RUNSTATS的频率。
Adjust the frequency of RUNSTATS depending on how fast data is changing in a table.
因此根据该数据转移的执行频率,wip_archive表的大小可以保持得相当小。
Therefore the size of the WIP_ARCHIVE table can be kept to a reasonably small size, depending on the frequency at which the transfer of data is performed.
数据中的模式:对于特定的表空间或分区,数据中重复出现的模式的出现频率将决定压缩的效果。
Patterns in the data: the frequency of recurring patterns in the data determines how effective compression will be for a particular table space or partition.
如果XML数据的访问频率与表中的其他关系值相当,那么这将提高查询数据的性能。
This gives a benefit while querying the data if XML data is accessed as often as other relational values in the table.
每当您有理由期望在生产数据中出现数据倾斜时,您就可能需要在测试数据中再现数据倾斜,首先,在一个表中存储预计频率。
Whenever you have a reason to expect data skew in production data, you might want to reproduce data skew in your test data. First, store the estimated frequencies in a table.
为每一个满足业务需求以及数据更新频率的IndexUpdateTask创建一个时间表。
A schedule should be created for each Index update Task that meets both the business requirements as well as how often the data is updated.
我读过的数据表,但找不到任何参考指定一个输入时钟频率。
I've read the datasheet but can't find any reference to specifying an input CLK frequency.
