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.
The explanation of consumer group to achieve queue and pubsub is gold. Thank you.
Lolll i Like the Jordan Peterson bit
Great video, entertaining, simple and educational at the same time. Subscribed and liked
Wish someone talks about Machine learning like you do with backend engineering. You are awesome.

This is amazing content! The one spoof in middle was pretty cool!
Wonderdul info Video about Kafka n its components
Thanks Hussein
Bro, you and Gaurav Sen are my two new favorite youtubers. Free high quality content. Awesome stuff! :D
DataSurgeon 369 Thank you! I love Gaurav content he is so passionate with his work
@@hnasr Yeah definitely, and he's pretty funny. That makes it a lot easier to say engaged.
This 15 mins video is better than a 2-hour lecture from my professor.
*7 min video (at 2x)
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.
Hussein is hands down the best at explaining complex topics. I love the light-hearted approach - hussein always FTW!
الله يعطيك العافية مبدع، شكرا جزيلا
Thanks so much for this video tutorial.
Very quick and deep explanation. You made it very interesting.
your explanation is chef kiss.
Thanks, Hussein, Great Job!
thank you so much, this video is very helpful. so easy for understanding
Wowww, your explanation is funny but easy to understand the concept. Many thanks.
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! =)
data pipelines are suffering
OMG you just use JB Peterson as a meme in a tutorial. Best combination for me !
You are guru, you are awesome, take a bow 🙇♀️👏
Best in world tutorial
Awesome explanation !
Very well explained.
You are a good teacher sir subscribed
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.
Thank you SemSem
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.
Good to know you too learn fron mr Peterson
Best starter video on Apache Kafka. One question: How is the order of message arrival maintained in different partitions?
"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
superb!!
Amazing videos , would be great if u can add these slides as well in desciption
Hussein, what is your opinion about beanstalkd? Compared with Kafka (used as a queue) which one would you prefer to and why? Thanks
Good work Huesein Ramadan Kareem
Thanks!
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.
Georgii Rychko thanks Georgii!! Will do
Thank you a lot!
I literally subscribed because of the Jordan Peterson reference 😂
Nice video. please add a video on activeMQ also
true gem
Hi Hussein! Great video! 👍 Can you please make a video on elastic search?
This should be next because sooo many requested it
@@hnasr Bro, still waiting for it
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?:)
Liked the Jordan Peterson clip !
🦞
Excellent video, Was expecting nodejs Kafka demo tho 😕
Hey Dean! Watch the full kafka video for the code 🙏
Something that I can't understand about Kafka are zookeepers, what are they? What are they used for? Where are they used? Its something that puzzle me
R. Rod. Aha you asked about the hardest piece in the puzzle that I cut from this video, checkout the full kafka video (end screen) I cover that in details
@@hnasr thanks for you answer, again your content is amazing teacher Hussien
@André Rosa what are paxos?
@André Rosa thank you sir for your answer
sorry for the question.. but it can be true that kafka seems to be the "facebook" of a distribuited system?
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?
Thanks that is correct, I do mention this in the full kafka video maybe this part was cut during this highlight.
Appreciate it
1000th LIKE. :D
One thing to keep in mind is that kafka hands "offset" which is a grest feature in case of kafka restarts
@t The Bucket Rider: From Kafka to a Film Adaptation
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.
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
@@hnasr For eg. in the case that you mentioned, (N-Z) goes to partition 2, so Nader will automatically go to partition 2. Am l missing something here?
@@shiwang789 I agree the broker is absolutely capable of appending to the correct partition by looking at itself
lol Jordan Peterson has made it in the Kafka vid lol.
I feel partitions and sharding are completely different things
Wohooo I got published xDDDD
🇧🇩🇧🇩🥰🥰
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 CZcams here czcams.com/video/O1PgqUqZKTA/video.html
Thanks for being long time subscriber and asking great questions over the years Vrunda.
@@hnasr I have built a game. It uses subscription provided by Firestore. game.cvfy.in - Will Kafka be useful in replacing Firestore?
The game is if Bingo. So, random numbers between 1 and 90 are shown to players and they claim dividends. So, it's all players are on subscription to one document where updates happen.
Let's give credit where it truly belongs, "Life is Suffering" - The Buddha, 2500 BC
So... what is Kafka?
Why do u suddenly change ur accent to Spanish when explaining about Partition?
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.
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.
Right after your rant on suffering, I got hit with a st Jude’s commercial about children with cancer 🫥
