Got to understand kafka by following your tutorials. So clear explanation!! You are great😇

[SivaChaitanyaReddySanivarapu]

Great topic, we are using this in my billing project

[piwvjnj]

just started watching your video of kafka today at 10 am morning. I couldn't stop myself and its 2 am next day just completed your all videos of kafka with hands on. Just one suggestions keep your kafka consumer topic in kafka playlist otherwise many can miss tracking this .Also i'm waiting for other kafka topics like kafka connect with database where messages are being received from different source system which kafka server listen and stores those in our database and vice versa

Nice Basant, Keep going with this series...

[AleksandarT]

Great video!
Explains how Kafka Consumers work pretty clearly. As an idea for the next video/s, you can go over more of the properties of Kafka for Producers/Consumers - and explain concepts like batching, the most common properties that can be configured (like manual acknowledgement or not) etc

[ankurverma]

awesome explanation able to learn the whole very well. Thank you

[LearncodewithMuneeb]

Thanks sir for making useful videos for us.
But I request you very respectfully to work in a project in spring boot having at least 6 entities/tables using spring boot in the back end and React/Angular/Next in the front end

Nice explanation. Can you cover in upcoming videos like how can we replay or retry lagged messages and how to identify which messages lagged and how to replay those .

[appstude]

thank you for the video. can please tell me what's will happen if you start kafka-consumer-example project twice ? how many consumer will have ? 3 consumer in each instance ?

[Gsuresh_]

Hello, Recently I faced a question in interview, if I give a java project along with remote server without any IDE how you run that project. Can you make a video on it

[xwsddtj]

Good Explanation basant. Great work. I have one quick question you change the group id in the java class but not changed in yml still application works fine. Then what is the point of adding the group id in yml.

[dhamodharankrishnamoorthi]

How i can create multiple consumer group, and consume message concurrent please explain

[geekdeb]

Great, If you can enlighten on the real time project prospective, it would be great

[cdulnsq]

Hi can you create videos on Kafka stream?

[gauravsrivastava]

Hi Basant !! Can you please all the necessary videos of this particular Kafka series to a YouTube Playlist. It will make it easy to access all relevant videos from one place. And as and when you create new videos, you can add them to the playlist. Thanks!

[pyxletc]

thank you for your tutuorial easy to understand
but i have question is it possible to miss data in kafka between producer and consumer process
if it likes that how can i avoid missing data

[vaishalis]

Hi Basant, thank you for an excellent informative video. What I do not understand about the lag is, if Kafka stores the messages for minimum one week, then why do we have to republish the messages which are in the lag. Why it will not automatically be reprocessed when the consumer is back up and running?

[VIKASSINGH-jfjd]

Basant. How do you create this beautiful presentation ? Which tool do you use or animation ?

[pnamm]

Great video. Can you cover avro schema and retry mechanism and also how handle any exception when processing message consumption?

[RochaNahuel]

The example is clear and I like it, but these 3 consumers who are listening to the same topic and working together, could call the same method of the logica layer without problems ?
