How to efficiently fetch related records in MySQL for a React frontend?
Hey everyone, I'm running into an issue that's driving me crazy. I can't seem to get Building an application that displays user profiles and their associated posts, I need to ensure that loading times remain optimal. Currently, I have two tables: `users` and `posts`, linked by a `user_id` foreign key in the `posts` table. A naive approach I tried was this simple query: ```sql SELECT users.id, users.name, posts.title, posts.content FROM users JOIN posts ON users.id = posts.user_id; ``` While this works, fetching all posts for all users at once is dragging performance down significantly, especially as the user base grows. Attempting to address this, I set up pagination for loading posts, but the experience isn't seamless. My current implementation uses a limit and offset, like so: ```sql SELECT users.id, users.name, posts.title, posts.content FROM users JOIN posts ON users.id = posts.user_id LIMIT 10 OFFSET ?; ``` However, users still face delays during interaction. Looking for the best way to improve this, I considered caching strategies using Redis but am uncertain how to implement that effectively with MySQL data retrieval. Additionally, I thought about fetching user profiles separately and then fetching posts on demand when a user clicks on their profile. This could lead to multiple network requests, which might not be ideal either. What would be the recommended approach to optimize loading user profiles with their posts in MySQL for a smoother user experience in my React application? Are there best practices for batching these requests or leveraging caching without overcomplicating the database interactions? My team is using Sql for this CLI tool. Any help would be greatly appreciated! I'd really appreciate any guidance on this.
