Hello, foo I need to apply circuit breakers in the project I'm currently working on, and at first, the team suggested introducing Hystrix. As shown in the lecture video, the project is only maintaining Hystrix, so I shared this with the team and was going to introduce Resilience4j, and a related lecture came out, so I took it right away! I took another lecture by foo before, and it was really helpful, and this one was also very helpful. I'm really grateful, and I hope you'll give me more great lectures in the future! Thank you!
