Redis Database Consistency Methods

There are several ways to keep Redis and database data consistent.

1. By using a message queue, you can send messages to the queue when data changes in the database, then subscribe to these messages in Redis to synchronize and update the data in Redis.
2. By using scheduled tasks, you can regularly check for any changes in the database and sync the updated data to Redis.
3. Utilize cache avalanche: you can take advantage of the cache avalanche mechanism to reload the data from the database into Redis after the cache expires, ensuring data consistency.
4. By employing database triggers, you can automatically synchronize the changes in data to Redis when they occur in the database.
5. Utilizing distributed transactions ensures consistency between data in databases and Redis by updating both simultaneously when the transaction is committed.
