When you answer the question then please repeat the question first as question is not audible to us so it is bit of a guess work to get the question correctly.

Why did they not change the message format (internaly) and store the flags in some "Meta Field" of each message? This would leave the offsets as they were...

funny how FSO is problematic for pointing when it's about G2A links - where at least the ground station is stationary and stable, but totally acceptable for A2A links, where both ends are moving and subject to vibration and wind speeds up to 30/s. but 10urad accuracy is indeed pretty impressive.

Another question, how do we make sure these abort markers are safely written to the topic partitions? If they never made it to the partitions, we could have duplications correct? Just curious.

How does the Kafka producer know the sequence number to send along with the message to broker? What happen if we have multiple producers sending to the same topic at the same time? How does it guarantee idempotency in this situation?
@anticipayo 4 жыл бұрын
Each producer would have a different producer id.
@BloodnutXcom 3 жыл бұрын
The producer starts from 0 and increments as it writes. it doesn't have to remember it's seq "offset" in case of crash because he's getting a new ID anyway from the broker on startup.
