不会出现为空的情况，redis重置key数据的时候会加锁， 所以不会出现为空的情况，但会出现一定一定的阻塞现象
会。有一定可能
redis是单线程的，所以咯，有啥问题？

The Future of PHP: Adaptations and Innovations
Apr 11, 2025 am 12:01 AM
The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.
How to build the redis cluster mode
Apr 10, 2025 pm 10:15 PM
Redis cluster mode deploys Redis instances to multiple servers through sharding, improving scalability and availability. The construction steps are as follows: Create odd Redis instances with different ports; Create 3 sentinel instances, monitor Redis instances and failover; configure sentinel configuration files, add monitoring Redis instance information and failover settings; configure Redis instance configuration files, enable cluster mode and specify the cluster information file path; create nodes.conf file, containing information of each Redis instance; start the cluster, execute the create command to create a cluster and specify the number of replicas; log in to the cluster to execute the CLUSTER INFO command to verify the cluster status; make
PHP vs. Python: Understanding the Differences
Apr 11, 2025 am 12:15 AM
PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.
PHP: Is It Dying or Simply Adapting?
Apr 11, 2025 am 12:13 AM
PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.
How to implement the underlying redis
Apr 10, 2025 pm 07:21 PM
Redis uses hash tables to store data and supports data structures such as strings, lists, hash tables, collections and ordered collections. Redis persists data through snapshots (RDB) and append write-only (AOF) mechanisms. Redis uses master-slave replication to improve data availability. Redis uses a single-threaded event loop to handle connections and commands to ensure data atomicity and consistency. Redis sets the expiration time for the key and uses the lazy delete mechanism to delete the expiration key.
What to do if redis-server can't be found
Apr 10, 2025 pm 06:54 PM
Steps to solve the problem that redis-server cannot find: Check the installation to make sure Redis is installed correctly; set the environment variables REDIS_HOST and REDIS_PORT; start the Redis server redis-server; check whether the server is running redis-cli ping.
How to view all keys in redis
Apr 10, 2025 pm 07:15 PM
To view all keys in Redis, there are three ways: use the KEYS command to return all keys that match the specified pattern; use the SCAN command to iterate over the keys and return a set of keys; use the INFO command to get the total number of keys.
How to read the source code of redis
Apr 10, 2025 pm 08:27 PM
The best way to understand Redis source code is to go step by step: get familiar with the basics of Redis. Select a specific module or function as the starting point. Start with the entry point of the module or function and view the code line by line. View the code through the function call chain. Be familiar with the underlying data structures used by Redis. Identify the algorithm used by Redis.
