Article Introduction：Redis and database are different data storage systems. Redis is an in-memory database that emphasizes high-performance reading and writing and flexible data structures, while the database is a persistent database that emphasizes data persistence and structured queries. Therefore, they can be used complementary, with Redis serving as a cache or temporary storage to accelerate database read and write operations and reduce database pressure.

Article Introduction：Redis and database data consistency maintenance can be achieved in the following ways: regular data synchronization using Redis publish/subscribe mechanism using Redis transactions using Redis Sentinel or Redis Cluster. Notes include: synchronization frequency, database transaction support, data consistency monitoring and regular inspections.

Article Introduction：The way redis implements synchronization with the database: the first access obtains data from RDBMS and saves it to redis, and the second access retrieves data from redis. For those with high consistency requirements, read from the database, such as financial data; other reads from Redis .

Article Introduction：No, Redis is not a database in the traditional sense. It is an in-memory key-value store used for purposes such as caching, messaging, and session management, but lacks database features such as persistence, transactions, structured data, and query languages.

Article Introduction：Multi-database operations with Redis and PHP: How to implement data partitioning Redis is a fast, high-performance key-value storage database that is often used to cache data and handle high-concurrency operations. In practical applications, we often need to process large amounts of data, and a single Redis database may not be able to meet our needs. Therefore, using multiple databases for data partitioning is a very common solution. This article will introduce how to perform multi-database operations through PHP and Redis to achieve data partitioning. 1. Redis

Article Introduction：Redis and MySQL databases can be used complementaryly. The advantages of Redis include fast speed, caching data, and suitability for session management and leaderboards, while MySQL is suitable for complex queries and transaction support. They can be used together, with Redis used as a cache or messaging system and MySQL used as the primary storage. It should be noted that Redis will lose data when the server is restarted, so important data needs to be persisted to MySQL.

Article Introduction：Redis database supports a variety of data types, including: string, hash, list, set, sorted set, stream, bitmap, geospatial, and HyperLogLog. Choosing the appropriate data type depends on data structure, access patterns, and space efficiency. With careful selection, Redis can be optimized for performance and storage efficiency.

Article Introduction：Redis is a key-value store database that stores and retrieves key-value pairs and provides high-speed memory-based data access, but is volatile. Additionally, it provides unique features such as data structure diversity, atomicity, durability (optional), publish/subscribe, and transactions.

Article Introduction：How to use PDO to connect to the Redis database. Redis is an open source, high-performance, in-memory storage key-value database that is commonly used in cache, queue and other scenarios. In PHP development, using Redis can effectively improve the performance and stability of applications. Through the PDO (PHPDataObjects) extension, we can connect and operate the Redis database more conveniently. This article will introduce how to use PDO to connect to a Redis database, with code examples. Install the Redis extension at the beginning

Article Introduction：No, Redis is not a relational database. It uses key-value storage, in-memory data structures, and a high-performance design to support caching and messaging, but lacks the tabular structure, relational model, transaction processing, and SQL query language of a relational database.
