public static <K,V> Stream<StreamUtils.Pair<K,V>> leftInnerJoinStream(Stream<K> stream,
                                                                                  Function<? super K,Stream<V>> mapper)
```
    Creates a stream of pairs that join two streams. For each element k from the stream and each element v obtained from the stream returned by the mapper for k, generates a stream of pairs (k, v).
    Effectively performs equivalent of a LEFT INNER JOIN SQL operation on streams.
    
    Type Parameters:
    
    K -
    
    V -
    
    Parameters:
    
    stream -
    
    mapper -
    
    Returns:
  - leftInnerJoinIterable

```
    Creates a stream of pairs that join two streams. For each element k from the stream and each element v obtained from the Iterable returned by the mapper for k, generates a stream of pairs (k, v).
    Effectively performs equivalent of a LEFT INNER JOIN SQL operation on streams.
