create a project for implementing any sdk in springboot like meet or zoom . this series is verry good

@45:35 architectiure is a overkill, but I understand in interview these things happen. Just like banks put some transactions in pending state as they want to run it batches or next day , in a similar way ecom also can reserve rather than assuming that a quantity is sold. There could be returns and refunds etc

Wow man what an explanation really you're a motivator for most of us. The way you are communicating with technical words are simply incredible. 💛

1:24:20 i think Spring Reactive web (Web flux) built on top of Reactor programming in that case we don't explicitly need Reactor dependency, we can straight away use Spring Reactive web dependency which is available in Spring inrializer itself 🎉 correct 💯 me if i am wrong
