- Method Detail
  - usingConcurrencyOf
```
@CheckReturnValue
public UniJoin.JoinFirstStrategyTerminal<T> usingConcurrencyOf(int limit)
```
    Limit the number of concurrent upstream subscriptions.
    When not specified all upstream Uni are being subscribed when the joining Uni is subscribed.
    Setting a limit is useful when you have a large number of Uni to join and their simultaneous subscriptions might overwhelm resources (e.g., database connections, etc).
    
    Parameters:
    
    limit - the concurrency limit, must be strictly positive
    
    Returns:
    
    an object to conclude the join strategy
  - toTerminate
```
@CheckReturnValue
public Uni<T> toTerminate()
```
    Forward the value or failure from the first Uni to terminate.
    
    Returns:
    
    a new Uni
  - withItem
```
@CheckReturnValue
public Uni<T> withItem()
```
    Forward the value from the first Uni to terminate with a value.
    When all Uni references fail then failures are collected into a CompositeException, which is then forwarded by the returned Uni.
    
    Specified by:
    
    withItem in interface UniJoin.JoinFirstStrategyTerminal<T>
    
    Returns:
    
    a new Uni
