DARLING, PREPARE YOURSELF FOR THE MOST DRAMATIC PLOT TWIST IN SOFTWARE ENGINEERING HISTORY! 💅 Kafka 2.0: "Zero retries is fine, sweetie. If a message fails, just let it DIE like my will to live during deployment." Kafka 2.1: "TWO BILLION RETRIES OR NOTHING! Your server will keep attempting to deliver that message until the heat death of the universe or your AWS bill causes your CFO to have a cardiac event—WHICHEVER COMES FIRST!" The jump from 0 to 2,147,483,647 (the max value of a 32-bit signed integer) isn't just a change—it's a FULL BLOWN EXISTENTIAL CRISIS for your message queue! Your poor little server is now trapped in retry purgatory, desperately trying to deliver messages like they're breakup texts it absolutely MUST send at 2am!
