@Acknowledgment(Acknowledgment.Strategy.MANUAL) doesnt seem to work

[samarism]

I am using this @acknowledgment(Acknowledgment.Strategy.MANUAL) and sending the ack manually after processin the record. BUT kafka keeps on sending messages without waiting for my ack. Why is it so? Please help. Thanks.

Assumption: quarkus should not call poll() method till i am done with processing the previous batch and have sent the acknoledgements for all the messages in the previous batch.

But seems that quarkus keeps calling poll() method, cause i keep on receiving messages.

It will continue calling poll until it runs out of requests.
