DescriptionWe give the following inductive definition of a "regular brackets" sequence:
The empty sequence is a regular brackets sequence,
If s is a regular brackets sequence, then (s) and [s] is regular brackets sequences, and
If a and b are regular brackets sequences, then AB is a re

In this test case, the partition COT_IND01_P37 contains nearly 10 million pieces of data, which takes nearly 7 minutes. If the partition data reaches 0.1 billion pieces, the time should be more than 1 hour. If the Hash Partition Number is an integer power of 2 recommended by Oracle, we will add a new partition that doubles the
