pavibhai opened a new issue, #7191:
URL: https://github.com/apache/iceberg/issues/7191

   ### Feature Request / Improvement
   
   ## What?
   Currently Iceberg does not support the use of the selected vector when 
reading ORC Files. This requires reads on ORC to be run in compatibility mode 
by not setting `orc.filter.use.selected` in the presence of filter processing 
that is triggered via `orc.sarg.to.filter`.
   
   Filter processing was introduced as part of 
[ORC-744](https://issues.apache.org/jira/browse/ORC-744) where ORC has the 
ability to filter out records and indicate this status in partially filtered 
batches using the selected vector in VectorizedRowBatch.
   
   ## Why?
   ORC can only operate in compatibility mode by not setting . Enabling this 
will further hasten the processing of rows by ignoring rows that are already 
filtered out in the batch.
