   <!-- Please specify the module before the PR name: [core] ... or [flink] ... 
-->
   
   ### Purpose
   
   <!-- Linking this pull request to the issue -->
   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.
