Hi, The at-least-once delivery is generated in part by the network fails and the retries (that may generate duplicates) right?
In the event of a duplicated (there was an error but the first message landed ok on the partition P1) the producer will recalculate the partition on the retry? is this done automatically? If in the retry the partition doesn't change and there is only 1 Producer, will the duplicated be written next to the original? I mean if I poll() they will come one after the other?
