Hi Basant,
Your videos helped immensely during the interview prep time and it helped to get a decent job as Senior Software Engineer... many thnaks to you !!

[umeshsharma]

Very creative and helpful video anyone can understand.
I went through many articles and videos, and I was very confused, and my thought was Kafka is very big and very vast. But by watching this video I am full cleared on Kafka concepts.

Hello @Java Techie, thank you for the amazing content, it is quite easy to understand. I have few queries,
1. What is the importance of replicationFactor?
2. How the kafka setup ensures delivery of message in case when consumer application is down?
3. Is it possible to create the topics from docker-compose.yml files?

[mubarakahmed]

Great knowledge sharing. Hope we can see multithreading consumer tutorial

[Vikusoun]

Hi Basant

Thank you for Kaka tutorial. Learned a lot from you in the fast. I have few queries

1. How can we create multiple topics programmatically? With @Bean we can create only topic at a time
2.. If topic already exist, it throws exception. How can we skip topic creation if topic already exist.
3. Does it creates new thread for each message send?

[akshaykumarr]

Please post a video for setting up the consumer for the same. Amazing video

[rohitmanohar]

Loved ur video, sir can u please make a video of inter service communication in spring Microserverices with real time example using kafka

[kishorejetty]

Also looks like the messages in kafka are getting encrypted by default, I dont see actual message in offset Explorer. Is ther a way to get plain message in kafka topic

[ravi.m]

Hi Basant, thanks for knowledge sharing.can you post video on replication factor other than one and how it will behave and in this case duplicate messages will be received by consumer or not

[SubhodipBasu-py]

How will we handle an exception and implement retry on the publisher microservice if we face issue while publishing to kafka

[SurajKumarSingh]

Thanks for this nice video, I have configured offset exproler but for me instead of actual message it showing hascode of message

[PradeepKumar-sxms]

Event Streaming with huge data reading and writing

[kishorejetty]

Have a quick question: if you are capturing the result into an object after sending, isn't that mean the thread will wait for result to come and it is still hampering the performance of the app ?
