[jira] [Created] (HIVE-26694) Populate file row position information during vectorized Iceberg reads

Ádám Szita created HIVE-26694:
---------------------------------

             Summary: Populate file row position information during vectorized Iceberg reads
                 Key: HIVE-26694
                 URL: https://issues.apache.org/jira/browse/HIVE-26694
             Project: Hive
          Issue Type: Improvement
          Components: Iceberg integration
            Reporter: Ádám Szita
            Assignee: Ádám Szita


Currently we leverage VectorizedOrcRecordReader and VectorizedParquetRecordReader during vectorized Iceberg reads. In order to read V2 tables where delete files with positional deletes are present, we need to make these record reader implementations provide the row number information too.
