Table data skew refers to a difference between the number of records in a table on particular database partitions and the average number of records across all database partitions for this table.
表数据倾斜指的是特定的一些数据库分区上的某个表内的记录数与这个表所跨的所有数据库分区的平均记录数之间的差额。
From the best practices perspective, the table data skew on every individual database partition should be no more than 10%.
从最佳实践的角度来看，各个数据库分区上的表数据倾斜应该不多于10%。
It then runs the same report for the existing data skew estimation and, at the end. drops the copy table.
例程然后会为了进行现有数据倾斜的估计运行相同的报告并且最后还会丢弃这个副本表。
Imitate data skew using an auxiliary table.
使用辅助表模仿数据倾斜。
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.
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。
You are either designing a new table that will be hash-partitioned, or you have an existing hash-partitioned table that might have a data skew problem.
