How to ensure data consistency between redis and mysql

In order to ensure data consistency between Redis and MySQL, the following strategies can be adopted: 1. Master-slave replication: Use MySQL's replication function to use MySQL as the master database and synchronize data to Redis as the slave database. 2. Transaction queue: Send update requests to the transaction queue, and the consumer applies them to MySQL and Redis in order to maintain data consistency. 3. API Gateway: All database update requests go through the API Gateway, ensuring updates are coordinated and applied in the correct manner. 4. Regular synchronization: Regularly use scripts or tools to synchronize data in MySQL to Redis to ensure data consistency. 5. Compromise:

How to solve the inconsistency between redis and mysql data

Methods to resolve data inconsistencies between Redis and MySQL include: Determining the source of the data inconsistency. Coordinate data consistency: transactional updates, distributed locks, event-driven updates. Data synchronization: asynchronous replication, periodic synchronization, incremental synchronization. Data verification: regular checks, introduction of verification mechanisms, use of unique identifiers. Fault tolerance measures: retry mechanism, data integrity check, redundant storage.
