Improving REST API Performance with Caching and Accessibility in Spring Boot
I recently switched to After trying multiple solutions online, I still can't figure this out. I've searched everywhere and can't find a clear answer. Building an application that adheres to accessibility standards while maintaining high performance can be challenging. Recently, I've implemented a Spring Boot REST API, and I’m looking to integrate caching mechanisms to improve response times without compromising on accessibility features. Currently, I’m using `@Cacheable` to cache responses, but I'm concerned about how this might affect dynamic content intended for users with disabilities. For instance, I have the following endpoint: ```java @GetMapping("/products/{id}") @Cacheable(value = "productCache", key = "#id") public ResponseEntity<Product> getProduct(@PathVariable Long id) { Product product = productService.findById(id); return ResponseEntity.ok(product); } ``` While this significantly boosts the performance when users request the same product multiple times, it raises questions about how updates to product information are reflected. If a product's description changes to include more accessible language, should I invalidate the cache? I've looked into using Spring’s `CacheEvict` for this purpose: ```java @PutMapping("/products/{id}") @CacheEvict(value = "productCache", key = "#id") public ResponseEntity<Product> updateProduct(@PathVariable Long id, @RequestBody Product updatedProduct) { Product product = productService.update(id, updatedProduct); return ResponseEntity.ok(product); } ``` However, I worry that frequent cache invalidation might negate the performance benefits I’m trying to achieve. To further optimize, I’m also considering using a Content Delivery Network (CDN) for static resources, but I need to ensure that the CDN’s cache doesn’t interfere with accessibility features like ARIA attributes. Does anyone have insights on balancing caching strategies with accessibility compliance in REST APIs? What best practices should I consider to ensure that performance enhancements do not hinder accessibility for users reliant on assistive technologies? Any thoughts on how to leverage caching without sacrificing the integrity of dynamic content for accessibility? For context: I'm using Java on macOS. This is part of a larger microservice I'm building. This issue appeared after updating to Java LTS. Has anyone else encountered this?
