Idempotent Producer

The video tutorial explains the concept of idempotent producers in Kafka, addressing the issue of duplicate messages caused by network errors. It describes how duplicate messages occur and how idempotent producers, introduced in Kafka version 0.11, solve this problem by using a produce request ID to detect duplicates. The tutorial also covers the necessary configurations and settings for using idempotent producers, such as retries and in-flight requests, and provides guidance on enabling this feature in Kafka.
