One unorthodox questions do you think creating those videos help you getting deeper understanding of these technologies. I write articles and I found that it actually benefits as much me as helping others. Great work.

[@AntonPutra]

thanks, of course it does

[@agun21st]

Wow, Anton sir, this breakdown of Apache Kafka's architecture is incredibly insightful! Understanding how topics, partitions, and brokers work together is key to leveraging Kafka effectively in real-world applications. Thanks for this great overview!

[@AntonPutra]

thanks!

[@GabrielPozo]

Thanks for this high-quality explanation!!!

[@AntonPutra]

thanks trying to improve

Great Kafka video, very clear and great diagrams.

Thanks!

best primer on Kafka. kudos

Awesome! I love these videos. They are so simple to understand. Thanks.

thank you!

[@soufiane22v]

Great video sir ! is it possible to create a video for deploying production-ready kafka clusters on k8s ?

[@zacclifton5479]

Well done! I would recommend doing Pulsar next

[@AntonPutra]

thanks! i'll take a look

Thank you. This was actually helpful :)

[@dimadiachenko1]

perfect explanation, ty

[@InvincibleMan99]

Hello brother Great explanation Recently in interview, i was asked what is the data structure that is used in kafka..

[@AntonPutra]

key/value :) for the value you can use RPC, avro, json etc.. Many companies use protocol buffers to reduce the size of the payload - grpc.io/docs/what-is-grpc/core-concepts/#service-definition

[@InvincibleMan99]

@@AntonPutra Got it thank you. Yeah so message data structure is key value. But as kafka is a queue, it maintains a log file in append mode on each broker, as you have covered. So it also has query data structure.

10:13 Kafka should work just as well with HDD, as it's writes are sequential, which is fast in HDD. If kafka needs SSD for fast performance, it will become very expensive to retain data in kafka for long periods, which is a feature kafka offers.

[@AntonPutra]

I doubt that it will perform well with an HDD, but I may test it someday

[@shokhrukhbekyursunjonov6203]

Good day Anton, thank you so much for user-friendly content! Could you please make a tutorial video on properly deploying secure (SASL/SCRAM) Confluent based full Fafka stack (2024 edition)? For several weeks I am attempting to deploy full kafka stack (zoo+kafka+schema-registry+kafka-connect+rest-proxy+ksqldb+conduktor-console) using SASL/SCRAM_SHA_256 method, but having errors in additional components such as registry, proxy connect and ksqldb during SASL SCRAM authorization... (docker compose solution). I am sure it would be really helpful to the kafka devops community here... Sincerely, Shokhrukh Yursunjonov

[@AntonPutra]

Sure, I can do it. A couple of questions: Is it Kubernetes-based? Also, why not use Kafka without ZooKeeper (KRaft)? Do you have any legacy applications that require ZooKeeper?

[@shokhrukhbekyursunjonov6203]

@@AntonPutra it is docker stack based (cause I am given one server to deploy kafka and I am writing compose file to deploy all in one server). Ah, I almost forgot about KRaft, good idea, I might try to use this mode, I heard that it is more intelligent and faster! According to my info (what devs said to me) apps are not legacy (mostly .net containerized apps), thus I can try using single/double broker KRaft mode, thank you. But I am afraid to have the same issues configurning SASL/SCRAM auth in it

[@AntonPutra]

@@shokhrukhbekyursunjonov6203 yes it's faster since kafka does not need to keep offsets in zookeeper and it's scales better without zk. I'll get to it maybe after EKS playlist will see.

[@suvajitchakrabarty]

In 4:55 should the partition in kafka broker 3 be partition 6, 7, 8 instead of 3, 4, 5, since you mentioned a partition always belongs to one broker.

[@AntonPutra]

yeah, copy paste mistake :) it should be 6, 7, 8

[@blender_wiki]

How you menage message locking in Kafka in case of a consumer task is time consuming?

[@RD-fb6ei]

So the upper bound on the number of consumers for a topic is the number of partitions? That’s quite limiting compared to something like Apache Pulsar or NATS Jetstream where you can horizontally scale the consumers as much as you want without worrying about the partitioning scheme of the server.

[@AntonPutra]

No, you can have as many consumers as you want, not limited by partitions. Depends on your app, in some cases, to scale you need to increase both partitions and consumers.

[@suvajitchakrabarty]

@RD-fb6ei However in those applications when you scale the consumers, I believe you lose the guarantee of events arriving in order.
