zhangjun0x01 opened a new issue, #1595:
URL: https://github.com/apache/incubator-paimon/issues/1595

   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar.
   
   
   ### Motivation
   
   The new version of the ORC format has done many optimizations, greatly improving performance,
   
   for example 
   https://issues.apache.org/jira/browse/ORC-744 
   
   
   Test | IO Reduction % | CPU Reduction %
   -- | -- | --
   Select 16 columns | 45 | 47
   SELECT * | 70 | 87
   
   
   So I think we should upgrade the orc version to improving query performance.
