The wrapped Beam.
Handler for successfully and unsuccessfully sent messages. Will be called from the same thread that you use to call 'send' or 'flush'.
Send a batch after receiving this many messages. Set to 1 to send messages as soon as they arrive.
Maximum number of batches that may be in flight before we block and wait for one to finish.
Send a single message.
Send a single message. May block if maxPendingBatches has been reached.
Wraps a Beam and exposes a single-message API rather than the future-batch-based API. Not thread-safe.
