Google Onsite Interview Question #14: Design a High-Throughput Thread-Safe LRU Cache with TTL

1. 1Design a basic LRU cache using a hash map and a doubly linked list
2. 2Implement thread safety using locks or atomic operations
3. 3Add a TTL (time-to-live) feature to expire cache entries
4. 4Optimize the cache for high throughput using techniques like caching frequently accessed items
5. 5Test the cache implementation using multiple threads and verify its correctness

Software engineers and system designers can benefit from this knowledge to improve their system's performance and scalability

💡 A high-throughput thread-safe LRU cache with TTL can be achieved by combining a hash map, doubly linked list, and atomic operations

💡 Design a thread-safe LRU cache with TTL for high-performance systems
