Caching can bring speed to the slow systems in your enterprise. In this session, we'll explore how to avoid expensive computations and reduce database (or other systems) load with caching. Considerations include when to cache (cache policy), how to cache, and when/how to evict. This session will also explore and discuss problems and gotchas like cache sizing, eviction mistakes, and where your cache should live. Finally, we'll look at how caching is implemented in the "memory-first" Couchbase architecture.
