### Question
Hi team,
Quick question about read parqeut rowgroup:
```
// FileIterator.class
private void advance() {
while (shouldSkip[nextRowGroup]) {
nextRowGroup += 1;
reader.skipNextRowGroup();
}
PageReadStore pages;
try {
pages = reader.readNextRowGroup();
} catch (IOException e) {
throw new RuntimeIOException(e);
}
model.setRowGroupInfo(pages, columnChunkMetadata.get(nextRowGroup));
nextRowGroupStart += pages.getRowCount();
nextRowGroup += 1;
}
```
Use ParquetFileReader.readNextRowGroup to retrieve all data, but do not use
columnindex.
May I ask if it is possible to optimize the use of
ParquetFileReader.readFilteredNextRowGroup here?
