Interface DictionaryEncodedStringValueIndex

All Superinterfaces:

DictionaryEncodedValueIndex<String>

All Known Implementing Classes:

IndexedStringDictionaryEncodedStringValueIndex

public interface DictionaryEncodedStringValueIndex
extends DictionaryEncodedValueIndex<String>

This exposes a 'raw' view into bitmap value indexes of a string DictionaryEncodedColumn. This allows callers to directly retrieve bitmaps via dictionary ids, as well as access to lower level details of such a column like value lookup and value cardinality. Most filter implementations should likely be using higher level index instead, such as StringValueSetIndexes, LexicographicalRangeIndexes, NumericRangeIndexes, or DruidPredicateIndexes
