Lock Granularity
Locking mechanisms can be implemented with different levels of granularity:
- Global Lock: A single global lock protects all cache entries. While this approach is straightforward, it can introduce contention and limit concurrency.
- Per-Entry Lock: Each cache entry has its own lock. This approach allows more concurrency but can lead to a high number of locks, increasing system complexity.
Note: The choice of lock granularity depends on the specific use case and the level of concurrency required.
How Cache Locks can be used to overcome Cache Stampede Problem?
Caching is a technique used to store data temporarily in a high-speed storage layer, such as memory or a dedicated cache, to reduce the latency and load on a primary data source, such as a database or a web service.
