[jira] [Created] (HIVE-26696) Implement row iterator for VectorizedRowBatch

---------------------------------

             Summary: Implement row iterator for VectorizedRowBatch
                 Key: HIVE-26696
                 URL: https://issues.apache.org/jira/browse/HIVE-26696
             Project: Hive
          Issue Type: Sub-task
          Components: Iceberg integration
            Reporter: Ádám Szita
            Assignee: Ádám Szita


In order to utilize the existing DeleteFilter implementation of Iceberg we'll need to provide a row iterator that iterates through the rows of a VectorizedRowBatch instance.

This can be used during a read with positional deletes, but it will be especially required for implementing equality deletes.

A HiveRow concept needs to be created along with a converter class that provides row data information that's usable as an Iceberg Record.
