has updated data a User A failed to delete cache for data a User B reads old data that is cached by data a At this point, the problem of inconsistent data arises.Solution Solutions1. Set the cache's effective time (the simplest scenario)Advantages: Simple Easy to operate Disadvantages: There will be old data in a short period of time If the amount of data is too large, the cache time is short, the cache is prone to a large number of failures during a

Cache consistency IssuesWhen data timeliness requirements are high, you need to ensure that the data in the cache is consistent with the database, and that the data in the cache nodes and replicas must be consistent, and that there is no difference. This is compared to relying on cache expiration and update policies. It is common to proactively update the data in the cache or remove the corresponding cache when the data changes.Caching Concurrency issuesAfter the cache expires, it attempts to ge
