this is one of the most annoying project videos to watch, you did not even care to expalin the algorithms and the thoughprocess behind your code let alone expalining how it afffects the UI. please make videos in detail taking as much time as you want rather than just reading code out of some unknown github repo and calming it to be a project video. To the serious students who want to learn and understand anything please skip this video just wasted 2 days of my time... insetead watch some 10-20 hour videos whith proper explaination you will actually learn something.

Great explanation 🌟

1. Topics can have multiple partitions. 2. Partitions can be thought of as log files or queues to which the messages get written to. 3. Only once processing is based on the acknowledgement received from the consumer that has consumed the task. 4. Effectively Kafka is a distributed Queue with messages guarantee. 5. Brokers can host multiple partitions corresponding to multiple topics at the same time

At 4:06, when you decided to use a loand balancer, wouldn't it have automatically meant you had multiple webservers? Is it possible to have a load balancer with 1 single webserver?

Very good explanation.

So we have a Worker Service for Adding Hotels to the DB but no worker service/booking queue for reservations? IMHO volume of reservations will be higher than the volume of hotel additions. Let me know if I'm missing anything. thanks.

can add video on raft also for kafka

I used to get confused with this stuff, like we use encoding algorithms to generate hash of the long url and now the generated hash is of smaller length, we store it and later we retrieve back. It has no complexity involved like that. Think about it this way, every time a request comes to shorten the url, you assign one number to it. First url --> 1 Second url --> 2 and goes on.. that's it.. and store this in mapping db, now get/1 gives you first url, get/2 gives you second url. 0,1,2...9 is the base 10 number. You got only 10 unique numbers to represent different urls, so it grows very quickly. For 1000 urls, you are already at 4 digits. And also generating urls 234233 is not human readable. So we use more mix of characters to represent a number, A-Z a-z 0-9, now for a fixed length of size 6. You can generate 62^6 combinations. Just split this range for a different webservers, they keep on incrementing and maps it to url and store in the DB. Now when the get request comes, you know where it is in DB.

Thanks for this project. I completed it. Whenever I stuck I take github as reference. Thanks for putting that too.

Very good explanation! Which tool do you use to create the video?

KRaft

Nice explanation but there is just one problem: I'm pretty sure a zookeeper is someone who take care of a zoo

Happy to find your channel, looking forward to system design videos

very nice :) one comment tho, voice seems like in 1.25 speed and words often are barely understandable. Would appreciate a bit more effort in pronunciation

Boooring. Bad teacher "

could you give us a sample case on which algorithm is better than another?

Thanks Bro!

I would not say dynamic/flexible shema is an advatage of nosql. It is just a trait. Which can really hurt if used the wrong way.

I feel like your channel and contents are so undervalued.

What is Task?

your videos are amazing! I always come here to study for my interviews

Good, but this would have benefitted from a few more minutes of a quick example of each, and brief explanation of 'why' some approaches are faster, more flexible, etc.

please make video how to database migration

Id like to see comparison between similar apps like rabbitmq

oops there was a video on instagram! amazing

great content! It would be cool to see a social network like Instagram

wow this is really well done! thanks a lot. Just began working on a new project and need to come up with a good architecture, I learned quite a bit.

That was nicely explained. I recently combined token bucket and fixed window algorithms in one of my Springboot microservices. I used Semaphore for Tokens and checked if the number of requests made in 1 minute did not exceed the allowed requests on the Blackline API.

The tutorial is great, especially visuals. Which software is used to create such content?

Nice one. Keep up the good work. Your channel will explode one day.

Now I can flex my knowledge to my clueless friends 😅😂

Excellent ...thanks a lot , love from India

What if the target was the gateway? For example DDOS

So, java is interpreter because It compiles to intermediate code particularly bytecode

Nice video, I appreciate all the visuals you added. Keep it up!

Great content! Keep it up!

Excellent , thanks a lot ,

Underrated channel, keep up the great content!

Good work. This is just a reminder that every system design requires a deep investigation of the domain model. Please do not dive into design without understanding the challenges of your domain model. For example, most hotels and bed banks struggle to calculate availability and generate offers. You need to define markup policies, other details, etc. This kind of content can help you understand system design, but that doesn't mean you can use it in prod. env :)

Great video! what tool do you use to make your diagrams?

Great video! Thank you

Very cool explanation. I would like to see a system design of Trutpilot. How would you do reviews at scale.
