Looking at the reactiveMongo documentation - bulkInsert - Future[Int]

defbulkInsert[T](enumerator: Enumerator[T], bulkSize: Int, bulkByteSize: Int)(implicitwriter: BSONDocumentWriter[T], ec: ExecutionContext): Future[Int]

What is the return value of Future[Int], I am assuming that it's equivalent to the size of the Enumerator i.e the total number of elements. Any thing other than the totalnumbers is  considered a failure ?.

It is supposed to return a number of successfully inserted documents. 

Be aware of default maximum sizes for bulk insert (default max size for a bulk is 1MB, default max docs number for a bulk is 100.
