StringComparators.NaturalComparator (druid-processing 30.0.1 API)

java.lang.Object
- org.apache.druid.query.ordering.StringComparator
- - org.apache.druid.query.ordering.StringComparators.NaturalComparator

All Implemented Interfaces:

Comparator<String>

Enclosing class:

StringComparators
```
public static class StringComparators.NaturalComparator
extends StringComparator
```
NaturalComparator refers to the natural ordering of the type that it refers. For example, if the type is Long, the natural ordering would be numeric if the type is an array, the natural ordering would be lexicographic comparison of the natural ordering of the elements in the arrays. It is a sigil value for the dimension that we can handle in the execution layer, and don't need the comparator for. It is also a placeholder for dimensions that we don't have a comparator for (like arrays), but is a required for planning
