Review Summary
Your implementation successfully meets all functional requirements. The AsyncRequestProcessor correctly uses CompletableFuture and ConcurrentHashMap for thread-safe async caching, the Main class properly orchestrates concurrent processing with an ExecutorService of 3 threads, and the caching logic correctly serves repeated user1 requests from cache. The only failing check is a minor style issue: AsyncRequestProcessor.java is missing a trailing newline character at the end of the file. This is a checkstyle/formatting requirement from the mate-academy style guide and doesn't affect code functionality. Simply add an empty line at the end of the file to resolve this. All core requirements are implemented correctly — the solution is approved.

Review Summary
Your implementation successfully meets all requirements. The AsyncRequestProcessor correctly uses CompletableFuture and ConcurrentHashMap for async processing with thread-safe caching. The Main class properly orchestrates concurrent processing with a 3-thread pool, and the cache-first lookup ensures repeated user1 requests are served efficiently without the 1-second database delay. The previously noted trailing newline issue has been resolved. All functional requirements are satisfied.
