How do batch.size, linger.ms, and max.in.flight.requests.per.connection affect producer throughput and message ordering guarantees?

How do batch.size, linger.ms, and max.in.flight.requests.per.connection affect producer throughput and message ordering guarantees?

• A. Larger batch sizes increase throughput but add latency; linger.ms controls batching delay; max.in.flight.requests.per_connection limits in-flight requests and affects EOS guarantees.
• B. Batch size and linger.ms have no effect on throughput; max.in.flight has no effect on throughput.
• C. Larger batch sizes decrease throughput and increase latency.
• D. Increasing batch.size reduces latency.

Answer: (C)
