    Description

              if (useDecimal64ColumnVector) {
          this.batch = deleteDeltaReader.getSchema().createRowBatchV2();
        } else {
          this.batch = deleteDeltaReader.getSchema().createRowBatch();
        }

      Is creating a fully wide row-batch, despite the fact that all row columns have to be NULL in a delete delta.

      createRowBatch() should follow includes and avoid over-allocating column vrbs.
