How do mysql and redis ensure double-write consistency?
Technologies to ensure double-write consistency of mysql and redis include: 1. Transactional update: update mysql and redis at the same time to ensure consistency; 2. Master-slave replication: changes on the mysql master server are synchronized to the redis slave server; 3. Event-based updates :mysql records changes and sends to redis and so on. This topic provides you with relevant articles, downloads, and course content for you to download and experience for free.
How do mysql and redis ensure double-write consistency?Technologies to ensure dual-write consistency of MySQL and Redis include: transactional update: update MySQL and Redis simultaneously to ensure consistency; master-slave replication: changes on the MySQL master server are synchronized to the Redis slave server; event-based updates: MySQL records changes and sends them to Redis; timestamp comparison: update Redis based on the newer timestamp of MySQL; third-party middleware: use middleware to send MySQL changes to Redis for update.
Comparative analysis of MySql and Redis: How to choose a suitable database according to high concurrency scenariosWith the rapid development of the Internet, more and more enterprises and developers are facing the challenge of high concurrency processing. In this context, how to choose a suitable database has become an important issue. In this article, we will compare and analyze two common databases-MySql and Redis, to help readers choose a suitable database according to different high-concurrency scenarios. MySql is a relational database that is popular for its stability, scalability and mature technology ecosystem. In contrast, Redis is a memory-based
How to ensure the double-write consistency of mysql and redis1. Scenario: Double-write consistency means that when we update the data in the database, the data in redis must also be updated synchronously. The process of reading data using redis. When the user accesses the data, the data will be read from the cache first. If the cache is hit, the data in the cache will be directly returned to the user. If there is no data in the cache, the database will be queried first. Save the queried data to the cache and then return it to the user. 2. Strategies to ensure double-write consistency 1. Update the cache first, then update the database 2. Update the database first, then update the cache 3. Delete the cache first, then update the database 4. Update the database first, then delete the cache Three, four strategies Advantages and Disadvantages 1. Update the cache first, then update the database. The problem is obvious if the cache is updated.
What are the differences between MySQL and Redis?Differences: 1. MySQL is a relational database; Redis is a non-relational database. 2. MySQL is used to persistently store data to the hard disk, which is powerful but slow; while Redis is used to store frequently used data in the cache and has fast reading speed. 3. MySQL data is stored on disk; Redis data is stored in memory. 4. MySQL’s commonly used data types include numerical values, date/time, and strings; Redis’s commonly used data types include strings, Hash, List, Set, and Zset.
