Why Producers Need Retries Network errors, leader elections, and broker restarts are normal events in a distributed system. Without retries, a transient broker hiccup causes permanent data loss from the producer’s perspective. With retries, the producer automatically re-sends failed records until either the broker accepts them or a timeout deadline is reached. sequenceDiagram participant Producer participant Leader as Leader (Broker 1) participant NewLeader as New Leader (Broker 2) Producer->>Leader: ProduceRequest (offset 42) Note over Leader: Broker 1 crashes mid-write Leader--xProducer: No response (timeout) Note over Producer: retry.
