EncodingStats (Apache Parquet Column 1.15.2 API)

```
public class EncodingStats
extends Object
```
EncodingStats track dictionary and data page encodings for a single column within a row group. These are used when filtering row groups. For example, to filter a row group based on a column's dictionary, all of the data pages in that column must be dictionary-encoded. This class provides convenience methods for those checks, like hasNonDictionaryEncodedPages().
