Purpose
At present, Python's statistics directly calculate each column of data, which has a relatively high computational cost. Moreover, the calculated min and max are not truncated to the longest 16 bytes like in Java, resulting in significant Manifest storage overhead.
We directly disabled the statistical information of value and only retained the statistical information of the primary key.
