Apache Kafka - Real-time Stream Processing (Master Class) - Advanced Kafka Producer (Implementing Transaction)

The video tutorial introduces the concept of a transactional producer in Kafka, which extends the idempotent producer by providing transactional guarantees. It explains how to set up topics with the necessary configurations for transactions, including replication factors and min In Sync replicas. The tutorial covers the importance of setting a unique transactional ID for each producer instance and the steps to implement transactions, such as initializing, beginning, committing, and aborting transactions. Finally, it demonstrates testing the transactions and provides key insights into handling transactions in a multithreaded environment.
