I enjoyed the lecture, instructor! I listened to the theory part maybe two weeks ago, but I kept putting it off and finally finished the practical part just now... Honestly, for the last Lua script part, I stopped typing along and just watched the lecture... 😊😊 (Oh, so this exists... but I probably won't use it right away...? 😊😊..) Overall, I think the lecture is good for developers with no experience when integrating Redis with Spring Boot! True to the instructor's philosophy of providing a broad direction, just like your reply to my comment on the theory lecture last time, I think I've grasped the flow regarding redisTemplate / lua script / distribution lock! But as the instructor said, ultimately you have to study on your own, so based on this broad flow, I need to encounter more references and write actual code to apply Redis well in practice! (This part might be helpful for those considering taking the lecture! Rather than learning everything from A to Z, it's a lecture that teaches the big picture!) Because at my company, I was only using Redis as a simple means of asynchronous communication... (If the server I manage is A / and the server to integrate with is B) it's in the format where A reads values from the DB -> puts them into Redis as a hash -> and B reads them at the desired interval) Since I want to know more about typical use cases like caching / distributed locks, I think I need to study more ^^ Then I'll see you in the lecture [Job Search Story of an Idling Job Seeker and Server Optimization & System Design]~
