  -By default, `BulkProcessor`:
  -
  -* sets bulkActions to `1000`
  -* sets bulkSize to `5mb`
  -* does not set flushInterval
  -* sets concurrentRequests to 1
  -* sets backoffPolicy to an exponential backoff with 8 retries and a start delay of 50ms. The total wait time is roughly 5.1 seconds.

  +==== Closing the Bulk Processor
   
   When all documents are loaded to the `BulkProcessor` it can be closed by using `awaitClose` or `close` methods:
   
  
positive.code: all bulk requests to complete then returns `true`, if the specified waiting time elapses before all bulk requests complete,
  `false` is returned. The `close` method doesn't wait for any remaining bulk requests to complete and exits immediately.
  
  
negative.code: <5> We want to execute the bulk every 10 000 requests
  <6> We want to flush the bulk every 5mb
  <7> We want to flush the bulk every 5 seconds whatever the number of requests
  <8> Set the number of concurrent requests. A value of 0 means that only a single request will be allowed to be
      executed. A value of 1 means 1 concurrent request is allowed to be executed while accumulating new bulk requests.
  <9> Set a custom backoff policy which will initially wait for 100ms, increase exponentially and retries up to three
      times. A retry is attempted whenever one or more bulk item requests have failed with an `EsRejectedExecutionException`
      which indicates that there were too little compute resources available for processing the request. To disable backoff,
      pass `BackoffPolicy.noBackoff()`.
  
  By default, `BulkProcessor`:
  
  * sets bulkActions to `1000`
  * sets bulkSize to `5mb`
  * does not set flushInterval
  * sets concurrentRequests to 1, which means an asynchronous execution of the flush operation.
  * sets backoffPolicy to an exponential backoff with 8 retries and a start delay of 50ms. The total wait time is roughly 5.1 seconds.
