using Grafana k6, To know more about it, you can watch this video:ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TyktC6sPXn4.html IN this video I have shown how you can test your backend using Grafana k6
If you're wondering how data consistency will work in EDA-like we are showing a success message before the data is fully saved to the database-and how the post will become instantly available to others, and what if we have to do some validations like (authentication), you're thinking in the right direction! The short answer is: we’ll be using CQRS + a feed service along with some additional components (if needed). These strategies ensure smooth performance and handle scenarios like (validations) user authentication without overwhelming the database, even under high traffic. I’ll cover all these topics, including edge cases you might be thinking about, in the upcoming videos of this series. Stay tuned!
If we keep Kafka aside and consistency also aside if we are focusing on latency then doing the same bulk insertion logic at the producer level instead of using kafka, will also increase the latency so much right? Kafka is used for asynchronous tasks and consistency right? Can you clarify this doubt
Yes, doing bulk insertion logic at the producer level will significantly increase the latency because producers will be blocked waiting for database responses. Kafka solves this by decoupling the producer from the database, enabling asynchronous handling and smoothing out the load. Kafka is also used for event consistency and ordering, but a major benefit is how it helps systems scale with low latency by preventing blocking operations on the producer side
what if the the server gets down? the messages array will be destroyed... and cannot be entered into Kafka! if we use redis then if there are more then 1 severs then it'll create concurrency over control and it could add the same messages into the DB 3 times! Let's say we use RedLock for redis concurrency control then how can it control the lock in milliseconds? Could you answer it? And please make a video on it! Thanks ❤️
you are asking absolutely right questions and am happy you are following the video very closely. Short answer of your questions is : 👉CQRS - implemeting this for data consistency + feed service ( for instantly make posts available to other users ) Making a video on it very soon... stay tuned💖
Per me to python flask me kaam karta hu 😢 😂 chill h sir i am capable Enough to understand and implement same in any language (as long as same terminologies ka istmaal kara jaye). Me to adapt kar le ga 😂
solid and simple intro to kafka. ive seen many videos from which I can grasp the system design of an app like uber but haven't found a beginner friendly end to end system design similar to popular apps like spotify,uber lyft etc. This would be a great project to have on the resume as well as help in system design round. I'm trying to build one but it'll take a long time for me. So could you try making a video on this idea?
Sir it is requestes to make a big tutorial on creating an industry level EDA backend with full apis for admin and users.... I know it will take time but such 2-3 long videos will boost your channel. As there is a drought on such backend videos.... And you can take this drought as an opportunity
Yes bro, already working on this(Full stack project with EDA - Industry level Project)✅, you can also suggest project ideas that you want me to build with EDA ----
@@sandeepdev0 like youtube where you can do live stream with many people with live chat and upload large videos , streaming large videos with different quality and automatic adjust quality according to internet speed
