需要按分区键进行连接的表应该有相同数量的分区，并且应该在相同的值上断开。
Tables that will be joined on the partitioning key should have the same number of partitions and should break on the same values.
您有一个连接逻辑文件，但是只希望在SSD中保存键的索引，而不是二级索引。
You have a join logical file, but only want the index for the key on SSD, not the secondary indexes.
因此，任意键通常可以更快地执行连接。
Therefore, arbitrary keys will generally perform joins faster.
