- A quick introduction to how Apache Kafka works and differs from other messaging systems using an example application. In this video I explain partitioning, consumer offsets, replication and many other concepts found in Kafka.

Idk how many videos I went over but not a single one would say that partition in Kafka is JUST A QUEUE. They would unnecessarily make it complicated with more technical jargon.
Thank You good Sir🧔♂👋🎩
I felt the same ,bro 👍
Finally a tutorial using examples instead of abstract concepts. Thanks!
New kafka practical tutorial ..czcams.com/video/mlH0y7FOukU/video.html
I love how you don't just jump into the current implementation, but rather, goes through the thought process of starting out with single server setup, addressing issues, and then leading up to how Kafka handles it. Nice video. The videos help, the explanations are crystal clear and detailed too.
James, this is a great video. It goes to enough technical details and a perfect first video on Kafka. It should have a million views, really. Please keep posting and sharing your knowledge. Thank you.

You are right 👍
Hours of Kafka technology within 6 mins. And that too crystal clear. Hats off.
Would love to see more Kafka subjects communicated this way, awesome to give to a team to get basic concepts down.
This is exactly how an introduction to a tool should be made. Thanks James, liked and subscribed! I've seen a lot of these videos about user organisations and purpose, but not the exact problem they solved using this.
This 6 minutes made my day! What a crisp explanation. No bullshit straight and on point.
What an explanation. In 6 minutes so many details and so clear. This requires real talent
Wow! You created a great video - informative and concise. It gives enough technical details, but not too many in a short amount of time. Rarely do you see technical videos this well made on CZcams. Thank you.
What on earth was that? The most useful introduction I encountered to watch. Not only it addresses a lot of technical Q&As but also does it in a visual, perceptive and intuitive manner!
I was so struggling to understand why Kafka and this is it! to the point and crisp clear explanation . Thankyou !
Straightforward explanation in six minutes, thank you.
Hours of knowledge, juiced up in 6 minutes. Amazing video
Only a person who has deep knowledge on a subject can explain anything with clarity in a short video. Looking forward to more videos from you!
This is the best video hands down! I can see why Kafka is widely preferred because it's amazing distributed and fault tolerant architecture
Best intro to Kafka video I've seen. Thank you.
Thorough Notes
Apache Kafka is a solution to the problems faced by the distribution and scaling of messaging systems.
Kafka is used to design a system that listens to various basketball game updates from various sources and displays the game's status on various channels such as mobile devices and computer browsers.
In the architecture, a process called a producer reads these updates and writes them in a queue. Downstream processes called consumers consume these updates to display them on the various channels.
As the system expands to follow more games, the servers struggle to handle the load due to the queue being hosted on one server which is running out of memory and processing capacity.
To add more computing power, the architecture needs to be distributed. However, distributing a queue data structure can lead to consuming updates in the wrong order, resulting in inconsistencies.
Kafka allows the application to specify the way to distribute the items in the queue. In the example, items are distributed using the match name, ensuring that updates from the same match are on the same queue, maintaining an ordering per basketball match.
Each queue in Kafka is called a partition, and the total number of partitions is called a partition count. Each server holding one or more of these partitions is called a broker. Each item in a partition is called a record.
The field used to decide which partition the record should be stored in is called the partition key. If no key is specified, Kafka assigns a random partition.
A grouping of partitions handling the same type of data is called a topic. Each record in a topic is identified by a partition number and an offset.
Kafka allows for parallelizing consumer applications, with one consumer per partition guaranteeing ordering per game. Consumers can live on one machine or distributed amongst multiple ones.
Consumers in Kafka are lightweight and many can be created without affecting performance. Kafka only needs to maintain the latest offsets read by each consumer.
Consumers belonging to the same consumer group do not share partitions, meaning each consumer reads different records from the other consumers.
Kafka provides various policies that allow it to do a record cleanup. For example, using a retention policy, you can provide a record age limit after which the records are automatically deleted.
Kafka stores records in a fault-tolerant and durable way. Each record is stored on persistent storage so that if a broker goes down, it can recover when it comes back up.
Kafka replicates partitions so that when a broker goes down, a backup partition takes over and processing can resume. This replication is configured using a replication factor.
One of the best video to learn about Kafka basics … Simple and very clear , Thanks a lot
Very Helpful, explained in a very cleaned way. Thanks James for sharing this.
What a great video! Perfect balance between an illustrating example and technical depth. Easy to follow along.
I tried another video before, with which started out talking about "source systems" and "target systems", never explaining what they mean by those, without any illustrating example, and that video lost me right away. In contrast, yours easily made sense from the first second and was easy to follow along as you kept adding depth incrementally.
This is THE way to teach concepts as an introduction... I know because I already have questions about limitations and applications, and I'm thinking of a lot of other services that use something similar or actually are using K somewhere underneath; services I didn't REALLY understand, and now make much more sense. Thank you.
Hands down the best video introduction to understanding kafka in 6 mins, liked and subscribed
Simple clear and concise. Thank you James
The concepts are explained briefly but clearly. You have done in 6 minutes what most other "gurus" on yt are not able to do in 30 minutes. They go on talking and talking without really being able to hit the keys, probably because they don't themselves understand it.
extremely helpful to cover the base terms & workflow!!! brilliant piece! :D Thanks James
Thank you for the detailed example with the matches and the visualization, it really helps to understand the topic intuitively. Keep it up, James!
Very well done man, simplified demonstration
This is the fantastic video I ever watched on Kafka understanding.
Please make more such videos. Your content is good. Thank you for bringing this. The video is to the point.
Excellent video, great explanation and visual representation. Amazing job!
This is a perfect video explaining the core concepts of Kafka
James, really liked this tutorial! Concise with fantastic illustrations. Bravo
Thanks, James... Please post more videos. Precise and clear
Simple, clear and concise.. That's how teaching should be.. Kudos!
It started off clear, but got very confusing after half way.
@@fieryscorpion same feeling
but it seems like I am too stupid for now to understand the second part. this might be the reason
Best kafka intro so far. great video. thanks a lot
It was very well presented, in a simple and effective way. This put me on the page about Kafka technology.
