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🧔‍♂👋🎩

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.

Finally a tutorial using examples instead of abstract concepts. Thanks!

Would love to see more Kafka subjects communicated this way, awesome to give to a team to get basic concepts down.

What an explanation. In 6 minutes so many details and so clear. This requires real talent

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.

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 KZfaq. Thank you.

This 6 minutes made my day! What a crisp explanation. No bullshit straight and on point.

Hours of knowledge, juiced up in 6 minutes. Amazing video

Hours of Kafka technology within 6 mins. And that too crystal clear. Hats off.

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!

Very Helpful, explained in a very cleaned way. Thanks James for sharing this.

Straightforward explanation in six minutes, thank you.

I was so struggling to understand why Kafka and this is it! to the point and crisp clear explanation . Thankyou !

This is the best video hands down! I can see why Kafka is widely preferred because it's amazing distributed and fault tolerant architecture

extremely helpful to cover the base terms & workflow!!! brilliant piece! :D Thanks James

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!

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.

One of the best video to learn about Kafka basics … Simple and very clear , Thanks a lot

Hands down the best video introduction to understanding kafka in 6 mins, liked and subscribed

Excellent video, great explanation and visual representation. Amazing job!

Please make more such videos. Your content is good. Thank you for bringing this. The video is to the point.

Very well done man, simplified demonstration

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.

Best intro to Kafka video I've seen. Thank you.

James, really liked this tutorial! Concise with fantastic illustrations. Bravo

Watched many videos on Kafka but this is what i was looking for. Thanks for the simple yet effective tutorial for beginners. Loved it.

Simple clear and concise. Thank you James

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.

Thank you for the detailed example with the matches and the visualization, it really helps to understand the topic intuitively. Keep it up, James!

Your way of explanation is Outstanding!! Thanks and keep the good work flowing

Great video. Although I never use Kafka before, it is very clear for me to understand the its mechanism under the hood. Thank you.

Simple, clear and concise.. That's how teaching should be.. Kudos!

Great and very good summary of Kaffka in small amount of time

Transcript: Apache Kafka is the answer to the problems faced by the distribution and the scaling of messaging systems let me try to illustrate this by an example imagine we were to design a system that listens to various basketball game updates from various sources such updates might include game scoring participants and timing information it then displays the games status on various channels such as mobile devices and computer browsers in our architecture we have a process that reads these updates and writes them in a queue we call this process a producer since it's producing these updates onto the queue at the head of this queue a number of downstream processes consume these updates to display them on the various channels we call these processes consumers over time we decide to expand and start following more and more games the problem is that our servers are now struggling to handle the load this is mainly because the queue is hosted on one server which is running out of memory and processing capacity our consumers are also struggling in a similar fashion so now we start thinking of how we can add more computing power by distributing our architecture but how do we go about distributing AQ data structure by its nature the items in a queue follow a specific ordering we could try to randomly distribute the contents of the queue onto multiple ones if we do this our consumers might consume the updates in the wrong order this would result in inconsistencies for example the wrong scoring being displayed across the channels one solution is to let the application specify the way to distribute the items in the queue in our example we could distribute the items using the match name meaning that the updates coming from the same match would be on the same queue this strategy would maintain an ordering per basketball match this is the basic fundamental difference of Kafka from other messaging systems that is item sent and received Kafka require a distribution strategy let's have a look at some more detail and terminology used in Kafka each one of these queues is called the 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 and each item in a partition is called a record the field used decide which partition the record should be stored in it's called the partition key it's up to the application to decide which field to use as the partition key if no key is specified Kafka simply assigns a random partition a grouping of partitions handling the same type of data is called a topic in order to identify each record uniquely Kafka provides a sequential number to each record this is called an offset essentially a recording that topic is identified by a partition number and an offset in our application since we have now distributed our data in the topic using the name as the partition key we can now also parallelize our consumer applications having one consumer per partition guarantees ordering per game consumers can live on one machine or distributed amongst multiple ones one important concept in Kafka is that consumers are very lightweight and we can create many of them without affecting performance this is mainly because Kafka only needs to maintain the latest offsets read by each consumer typically consumers read one record after the other and resume from where they left after a restart however in Kafka it's up to the consumer implementation to decide on how to consume records it's quite common to have consumers to read all the records from the beginning on startup or to read the record in different orders such as reading back to front for example in Kafka each consumer belonging to the same consumer group do not share partitions this means that each consumer would read different records from the other consumers multiple consumer groups are useful when you have different applications reading the same contents in our example we could have a consumer group called mobile and another consumer group called computer these groups will read the same records but update different channels each consumer in these groups will have separate offset pointers to keep track which latest record was read if consumers can read using custom ordering how can Kafka determine that the record has been consumed and it can safely delete that record so it can free up space the answer is that tough comp provides various policies that allow it to do a record cleanup for example using irritation policy you can provide a record age limits say 24 hours after which the records are automatically deleted using this policy if your consumer application is never down for more than this age limit no messages are lost another capability of Kafka is to store 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 additionally 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 for example a replication factor of three leads to three copies of a partition one leader and two backups this means that we can tolerate up to two brokers going down at the same time Kafka can be a solution to your scalability and redundancy problems if the problem is well stated and the technologies are well understood there are of course a lot more technical and implementation details which can be found on kafkas documentation I hope that this short video has been helpful at providing an introduction but the fundamental concepts in Kafka if you like it please give it a thumbs up and subscribe.
