Kafka Consumer in Core Java | Without Spring Boot (From Scratch) (Ep 10)

In this video, we build a Kafka Consumer in Java using core Apache Kafka APIs, without Spring Boot.
Messages are published using kafka-console-producer so we can focus on Kafka consumer internals, including the poll loop, consumer groups, partitions, and offset management.

Topics covered:
- Kafka Consumer architecture
- Consumer group and partitions
- poll() loop explained
- Offset commit basics
- Running Kafka consumer with console producer
- Why Spring Boot is NOT used in this video

This video will help you truly understand Kafka consumers before using Spring Kafka.
