Increasing batch.size allows the producer to accumulate more messages into a single batch, improving compression and reducing the number of requests sent to the broker.

Increasing linger.ms gives the producer more time to fill up batches before sending them, which improves batching efficiency and throughput.

This combination is a best practice for maximizing throughput, especially when message volume is high or consistent latency is not a strict requirement.

Kafka ensures message immutability for data integrity. Once a message is written to a Kafka topic and persisted to disk, it cannot be modified. This immutability guarantees that consumers always receive the original message content, which is critical for auditability, fault tolerance, and data reliability.
