[jira] [Created] (ORC-1858) Add a c++ api that only get stripe level statistics without reading row group index

wushap created ORC-1858:
---------------------------

             Summary: Add a c++ api that only get stripe level statistics without reading row group index
                 Key: ORC-1858
                 URL: https://issues.apache.org/jira/browse/ORC-1858
             Project: ORC
          Issue Type: Improvement
          Components: C++, Reader
            Reporter: wushap
             Fix For: 2.2.0


The current implementation of the get stripe level statistics API reads the entire row group index of the stripe, which may introduce I/O overhead. 
To optimize this, we propose adding a new C++ API that retrieves stripe-level statistics without reading the row group index, thereby reducing unnecessary I/O operations.
