How to use the Transients API for caching

TransientsAPI is a built-in tool in WordPress for temporarily storing automatic expiration data. Its core functions are set_transient, get_transient and delete_transient. Compared with OptionsAPI, transients supports setting time of survival (TTL), which is suitable for scenarios such as cache API request results and complex computing data. When using it, you need to pay attention to the uniqueness of key naming and namespace, cache "lazy deletion" mechanism, and the issue that may not last in the object cache environment. Typical application scenarios include reducing external request frequency, controlling code execution rhythm, and improving page loading performance.

How to use object caching for persistent storage

Object cache assists persistent storage, suitable for high access and low updates, tolerating short-term lost data. 1. Data suitable for "persistence" in cache includes user configuration, popular product information, etc., which can be restored from the database but can be accelerated by using cache. 2. Select a cache backend that supports persistence such as Redis, enable RDB or AOF mode, and configure a reasonable expiration policy, but it cannot replace the main database. 3. Set long TTL or never expired keys, adopt clear key name structure such as user:1001:profile, and update the cache synchronously when modifying data. 4. It can combine local and distributed caches to store small data locally and big data Redis to store big data and use it for recovery after restart, while paying attention to consistency and resource usage issues.

How to implement role-based access control

The key to implementing role-based access control (RBAC) lies in rationally designing the correspondence between roles and permissions, and strictly implementing management processes. 1. Clarify roles and responsibilities, and start from the organizational structure or business process, define main roles such as administrators, editors, visitors, etc., to avoid overlapping permissions or "all-round roles". 2. Assign permissions to roles rather than users. Through permission points such as "Create articles", "Delete users", etc., set specific permissions for each role, and support users to bind multiple roles. 3. In terms of technical implementation, use existing frameworks such as SpringSecurity or Kubernetes to design roles tables, permissions tables and associated tables, and perform permission verification before key operations. 4. Regular review and update rights
