Retries and Max.in.flight.requests.per.connection

The video tutorial covers handling transient failures in Kafka producers, focusing on retry mechanisms, producer timeout settings, and delivery constraints. It explains the implications of retries on message order and introduces the concept of idempotent producers for better reliability. Key settings like retries, delivery timeout, and max inflight requests are discussed, providing insights into managing Kafka producer configurations effectively.

What is the default behavior of the retries setting in Kafka versions less than or equal to 2.0?

• The producer retries based on network conditions.

• The producer retries a fixed number of times.

• The producer does not retry automatically.

• The producer retries indefinitely.

How long will a Kafka producer retry sending messages by default before timing out?

• 1 minute

• 5 minutes

• 10 minutes

• 2 minutes

What setting should be adjusted to ensure strict message ordering in Kafka?

• Delivery timeout millisecond

• Producer timeout

• Max inflight requests per connection

• Retry backoff millisecond

What is a potential consequence of having a high number of inflight requests per connection?

• Increased data loss

• Higher network latency

• Reduced message throughput

• Messages being sent out of order

What is the recommended solution for maintaining message order in Kafka versions greater than 1.0?

• Adjusting the retry backoff millisecond

• Using an idempotent producer

• Increasing the retries setting

• Decreasing the delivery timeout
