Overview of Redis Redis (Remote Dictionary Server) is an open-source, in-memory data structure store used as a database, cache, and message broker. In high-concurrency environments, traditional relational databases often suffer from disk I/O bottlenecks and scaling limitations. Redis addresses these by keeping data in RAM and utilizing a highly ...

LRU vs. LFU Eviction PoliciesLeast Recently Used (LRU) and Least Frequently Used (LFU) are common cache eviction strategies. LRU tracks the time since last access, evicting the oldest entry when capacity is reached. LFU prioritizes access frequency, evicting entries with the lowest hit count. When multiple entries share the same minimum frequen ...

Route-Level Cache Control In RuoYi framework, you can prevent specific routes from using cached components by modifying the route configuration in src/api/router/index.js. Add the noCache: true parameter to the route's meta object: { path: '/storage', component: Layout, hidden: true, redirect: 'noredirect', children: [ { pat ...

The client-go caching layer relies heavily on the Indexer and ThreadSafeStore abstractions to maintain a local object store. This architecture minimizes direct API server requests by enabling efficient in-memory lookups and multi-dimensional indexing. Indexer Interface The Indexer interface extends the base Store contract by introducing retriev ...
