retries — Kafka Producer Configuration

Setting a value greater than zero will cause the client to resend any request that fails with a potentially transient error. It is recommended to set the value to either zero or `MAX_VALUE` and use corresponding timeout parameters to control how long a client should retry a request.

Tuning Recommendation

ProfileRecommendedWhy
producer / throughput2147483647Keep retries at MAX_INT (default since 2.1) and rely solely on delivery.timeout.ms to bound the total retry window; manually reducing retries can cause silent data loss on transient leader elections.
producer / durability2147483647Keep retries at MAX_INT (default since 2.1) and let delivery.timeout.ms govern the total retry window; manually capping retries can cause silent data loss during transient leader elections or ISR shrinkage events that resolve within seconds.
