Bro I literally went through entire documentation But this solved the consumer group concept in 5 mins 🙌

Now I know enough about Kafka after you video, thank you.

Lolll i Like the Jordan Peterson bit

The explanation of consumer group to achieve queue and pubsub is gold. Thank you.

Wish someone talks about Machine learning like you do with backend engineering. You are awesome.

Yeah. The idiot jobs that REQUIRE a degree... they're idiots and you don't want to work for fools. Smart people learn from any/every thing possible, and better than what schools offer.

OMG you just use JB Peterson as a meme in a tutorial. Best combination for me !

8:05 Absolutely love that Jordan Peterson reference about how life is suffering. That was awesome! And likely Jordan would add, the antidote to that is voluntarily confronting our own suffering will begin to cure it. Thank you for this Kafka educational video! I very much appreciate your teaching style! =)

Thanks, Hussein, Great Job!

You are guru, you are awesome, take a bow 🙇‍♀️👏

your explanation is chef kiss.

I have a question "Can the number of partitions changed during execution?" I did some research and share the answer here: 1. Number of partitions can be increased, but can not reduced. 2. When increasing number of partitions, Kafka servers are kept running. No code shut down time. 3. Rebalancing traffic is handled by Kafka, producer will send messages by the new partition and consumer will consume messages from new partitions too. Client does not need to handle the rebalancing.

man , u are awesome. i just wanted to know what Kafka is as it was mentioned in some topics related to my job and found ur video, loved ur explanation and simplicity. well explained bro.... keep it up man.

Wowww, your explanation is funny but easy to understand the concept. Many thanks.

Awesome explanation !

Best starter video on Apache Kafka. One question: How is the order of message arrival maintained in different partitions?

@ParthShah1504

"Kafka guarantees that messages from a single partition are delivered to a consumer in order. However, there is no guarantee on the ordering of messages coming from different partitions." - from the kafka's published paper

Best in world tutorial

Amazing! It would be really cool if you could make a video on Apache Kafka streams in NodeJS with demo examples, I’ve noticed that there are no proper resources on this subject.

Amazing videos , would be great if u can add these slides as well in desciption

Good to know you too learn fron mr Peterson

Very well explained.

Please describe a Replication factor and how can we add a new consumer group if there is no "free" replica but we need to do it?:)

Nice video. please add a video on activeMQ also

Just want to clarify: at 12:27, you said: "One partition'd better be consumed by 1 consumer" This only applies to consumers within the same consumer group, correct? Let's say we have: - 2 consumer groups G1 and G2. - G1 has consumer C1 and G2 has consumer C2 Can a partition P be consumed by both C1 and C2 since those consumers are from different consumer groups?

at 8:05 why do subscriber need to know which partition it is publishing the message to? The broker can itself figure out based on the rule of partitioning. And due to some case if it is not possible then do I need to change all my publish requests if add a partitions to an existing topic? That is a very bad design i think.

@hnasr

I think they made this flexible by allowing the publishing decide which partition, otherwise how would they configure the broker to decide which partition? But i agree with you it has its cost

Where is Kafka used. In which cases is it used?

When a simple request/response system isn’t cutting it. If the cost of calculating response is high OR if the same response is required by multiple requester services. having a pub/sub system helps in those cases (kafka is just one example) I give some use cases in KZread here kzread.info/dash/bejne/gWWEydOOob2xhKQ.html Thanks for being long time subscriber and asking great questions over the years Vrunda.

So... what is Kafka?

when your title says "What is", you don't start with explaining a component of the very thing you are trying to explain what it is.

Why do u suddenly change ur accent to Spanish when explaining about Partition?

Like for Jordan Peterson 👌

Sorry but this video is not well structured. I believe you know kafka, but you can't to explaint it

Jordan Peterson reference was cringe

Awesome! And as a side note: The world would be a better place if everyone studied the works of Jordan Peterson.
