Re: How producer gets the acknowledgement back

It may be too late to change the Producer API now.

I always find "ListenableFuture" is very nice/usable. It essentially adds
callback to Future. It's a lot easier to chain/combine ListenableFuture.

Hi,

In the new (Java) producer, you can pass in a callback function in the

Future send(ProducerRecord record, Callback callback)

call, which will be triggered when the ack is received.

Alternatively, you can also call Future.get() on the returned future
metadata, which will block until the ack is received (i.e., synced sending).

How producer gets the acknowledgement back

2014-09-24 Thread Sreenivasulu Nallapati
Hello,

Can you please help me to get the acknowledgement  in producer?


After setting the property  *request.required.acks to 1, *how producer gets
the acknowledgement back? I am trying to get the acknowledgement in java
producer.





Thanks
