      trevniMetas[i++] = new ColumnMetaData(column.getColumnName(),
          getType(column.getDataType().getType()));
    }


    writer = new ColumnFileWriter(createFileMeta(), trevniMetas);


    if (enabledStats) {
      this.stats = new TableStatistics(this.schema);
    }

    AvroColumnator columnator = new AvroColumnator(s);
    meta.set(SCHEMA_KEY, s.toString());           // save schema in file

    this.arrayWidths = columnator.getArrayWidths();
