How Kafka work internally?

[Kiran Singh <ki...@gmail.com>]

Hi

I am using producer API to send data to a topic. For this I am using
"metadata.broker.list" to specify my
broker list and i am able to send data successfully.

But i am looking for how Kafka server handle a producer API means
1. which broker act as a coordinator for the send request. As we know only
partition leader has the permission to write message into a partition.

But if i have topic with partition 3 and in my "metadata.broker.list" i am
pass only one broker details, even
then i am able to send my message.

2. Every send request will hit one broker in the list or Kafka use some
kind of load balancing to handle
send request.

Thanks
