DictionaryEncodedColumnMerger.ExtendedIndexesMerger (druid-processing 32.0.0 API)

All Known Implementing Classes:

StringDimensionMergerV9.SpatialIndexesMerger

Enclosing class:

DictionaryEncodedColumnMerger<T extends Comparable<T>>
```
protected static interface DictionaryEncodedColumnMerger.ExtendedIndexesMerger
```
Specifies any additional per value indexes which should be constructed when DictionaryEncodedColumnMerger.writeIndexes(List) is called, on top of the standard bitmap index created with DictionaryEncodedColumnMerger.mergeBitmaps(java.util.List<java.nio.IntBuffer>, org.apache.druid.collections.bitmap.BitmapFactory, org.apache.druid.segment.DictionaryEncodedColumnMerger.IndexSeeker[], int)
