I didnt understand one thing in builder pattern. What if we need to add another attribute to the static builder class like price? Do we need to modify the static class? How will we implement it?

Not clear. The problem you have mentioned and the solution as interface you have given is not in sync. For example, let say interfaceA has two functions which was impl by class B, now interface again need to change to add another 3 functions, this is impacting class B anyhow as it must impl those new three functions too.

Can I get the source code please?

Very well explained with examples. Easy to understand these concepts. One of the best content on System Design i have came across. As a beginner in System Design it really helping me to connect with day to day challenges in software system.

In big data and dedicated SQL server terms it gives a different meaning . Request to s set the base right before explaining .Also pls share ur reference documents and links

Awesome video !!! POST request explained by you made it a lot easier ....

How did you learn these things in the first place so that you are now able teach others? I ask because I have watched other videos from you, and I found the topics very informative and very well explained, but you must have learned all these things somehow.

I already told you first you learn then make videos. Don't post bewakoof saalaa videos.

At the time of implementation , do we need to create different project to implement circuit breaker pattern in between two services?

First you should learn then make videos. You half knowledge

He absolutely, positively would have failed a FAANG interview. He was not very articulate, haphazardly deciding what he was going to say as he was saying it. Many questions from the interviewer resulted in him having to toss out and redo a part of his design. He said the customer would track orders without saying a word about how or where orders themselves would be saved. He was going to debug the system by having redundancy in PayPal and nothing else.

Thank you very much

Thank you very much 🙏

Thank you very much

Thank you very much

Loved the content!

Could you please explain distributed tracing like MDC Sleuth

should we use queue for request-response ? why don't u use rest API for the request-response communication ?

Example at 11.57 - It won't be consistent right even if the system is taking all the 100 writes. Because until they reconcile, node A might have incorrect data, because what if the latest write happened in node B and not node A. I didn't understand why we considered read to be only taken by one node. It's anyway inconsistent (eventual consistency though). So Node A would also give wrong data, and Node B will also give wrong data.

How to solve distribution database problem?

Thank you very much

Thank you very much
