SearchableVersionedDataFinder (druid-processing 28.0.0 API)

Type Parameters:

DataDescriptor - The containing type for the data. A simple example would be URI
```
public interface SearchableVersionedDataFinder<DataDescriptor>
```
A class which implements SearchableVersionedDataFinder can find a DataDescriptor which describes the most up to date version of data given a base descriptor and a matching pattern. "Version" is completely dependent on the implementation but is commonly equal to the "last modified" timestamp. This is implemented explicitly for org.apache.druid.query.lookup.namespace.CacheGenerator If you have a use case for this interface beyond CacheGenerator please bring it up in the dev list.

```
DataDescriptor getLatestVersion(DataDescriptor descriptorBase,
                                @Nullable
                                Pattern pattern)
```
    Get's a DataDescriptor to the latest "version" of a data quantum starting with descriptorBase and matching based on pattern
    
    Parameters:
    
    descriptorBase - The base unit of describing the data.
    
    pattern - A pattern which must match in order for a DataDescriptor to be considered.
