Can acks=all cause production‑cluster failures when ISR shrinks?
Goal Produce messages with full durability guarantees while keeping latency acceptable in a multi‑broker Kafka cluster. Constraints and Uncertainty The producer is configured with acks=all and a replication factor of 3. In a local single‑broker test the write succeeds quickly, but in production the producer sometimes times out or receives a NotEnoughReplicas
