  - executeBatchRequests
```
CompletableFuture<Void> executeBatchRequests(AsyncRequestContainer<REQUEST> asyncRequestContainer)
```
    Execute a batch of async requests.
    
    Parameters:
    
    asyncRequestContainer - The AsyncRequestContainer which holds the given batch of processing requests.

    Execute a single async request *synchronously*. This is for synchronous APIs.
    
    Parameters:
    
    asyncRequest - the request to run.
  - fullyLoaded
```
boolean fullyLoaded()
```
    Check if this executor is fully loaded. Will be invoked to determine whether to give more requests to run or wait for a while.
    
    Returns:
    
    the count.
