The Heat Map displays values on either a clustered, linear or logarithmic scale, to help spot uneven distribution of data across threads.
“HeatMap”中能够以集群(clustered)、线性(linear)或者对数(logarithmic)的方式显示值,以帮助我们跨线程识别出对数据的不平均分布。
The large number of distinct values in the pdb_id column ensures a relatively even distribution of rows over the database partitions.
pdb_id列中各异的值数量很大,这就确保了跨数据库分区可以获得相对均衡的行分布。
The low mode populates only the scalar statistical values (that is, no distribution information) of a table.
low模式只填充表的标量统计值(也就是说,没有分布信息)。
