Application examples of Redis in mobile development
With the advent of the mobile Internet era, the development of mobile applications has become an increasingly popular technical field. In mobile application development, data caching is a very important link. Due to limitations in network transmission speed and stability, mobile applications need an efficient and reliable data caching mechanism to improve user experience. At this time, the Redis database has become the first choice for many mobile developers.
Redis is an open source memory data structure storage system. It supports a variety of data structures, including strings, hashes, lists, sets, ordered sets, etc., and supports transactions, persistence, clustering and other functions. . Therefore, Redis is very suitable for use as a cache database in mobile applications, improving the speed of data query and update, and reducing the frequency of network requests.
The following will introduce several application examples of Redis in mobile applications.
- User login information caching
In mobile applications, user login information needs to be verified and updated in real time, so an efficient caching mechanism is required. At this time, Redis can play a very good role. For example, whenever a user performs a login operation, the client will store the user information in Redis to quickly verify the user information. Whenever the user performs a related operation, the client will obtain the user information from the Redis cache to avoid frequent Access the database for query operations.
- Specific data query cache
In mobile application development, we often need to query some specific data, which may be popular product information within a period of time. , weather data of a certain city, etc. At this time, we can use Redis to cache this data. For example, whenever a user needs to query the weather data of a certain city, while the client accesses the city weather interface, the query results are cached in Redis. When the user queries the city's weather data again, the query results can be obtained directly from the Redis cache, which can reduce a large number of network requests and improve the efficiency of data query and update.
- Caching of chat information
In mobile applications, the chat function has become an important application function. For data storage of chat function, Redis can also play a good role. For example, we can cache each user's chat history in Redis, and whenever a user sends a message, the message is added to the corresponding chat history cache. This can reduce frequent access to the network and improve the real-time responsiveness of chat messages.
- Caching of data statistics function
In mobile applications, data statistics is also a very important function. For example, we need to count the number of times a certain product has been viewed, the number of times it has been added to the shopping cart, etc. All of these require data updating and calculation. The use of the Redis cache mechanism can avoid repeated calculation of data, reduce access to the database, and improve the efficiency of data statistics functions.
In short, Redis has many application examples in mobile applications, which can help developers build efficient and reliable data caching systems and improve user experience and mobile application performance. For mobile developers, mastering Redis application examples can make their mobile applications more complete and efficient.

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

How to clear Redis data: Use the FLUSHALL command to clear all key values. Use the FLUSHDB command to clear the key value of the currently selected database. Use SELECT to switch databases, and then use FLUSHDB to clear multiple databases. Use the DEL command to delete a specific key. Use the redis-cli tool to clear the data.

To read a queue from Redis, you need to get the queue name, read the elements using the LPOP command, and process the empty queue. The specific steps are as follows: Get the queue name: name it with the prefix of "queue:" such as "queue:my-queue". Use the LPOP command: Eject the element from the head of the queue and return its value, such as LPOP queue:my-queue. Processing empty queues: If the queue is empty, LPOP returns nil, and you can check whether the queue exists before reading the element.

On CentOS systems, you can limit the execution time of Lua scripts by modifying Redis configuration files or using Redis commands to prevent malicious scripts from consuming too much resources. Method 1: Modify the Redis configuration file and locate the Redis configuration file: The Redis configuration file is usually located in /etc/redis/redis.conf. Edit configuration file: Open the configuration file using a text editor (such as vi or nano): sudovi/etc/redis/redis.conf Set the Lua script execution time limit: Add or modify the following lines in the configuration file to set the maximum execution time of the Lua script (unit: milliseconds)

Use the Redis command line tool (redis-cli) to manage and operate Redis through the following steps: Connect to the server, specify the address and port. Send commands to the server using the command name and parameters. Use the HELP command to view help information for a specific command. Use the QUIT command to exit the command line tool.

Redis counter is a mechanism that uses Redis key-value pair storage to implement counting operations, including the following steps: creating counter keys, increasing counts, decreasing counts, resetting counts, and obtaining counts. The advantages of Redis counters include fast speed, high concurrency, durability and simplicity and ease of use. It can be used in scenarios such as user access counting, real-time metric tracking, game scores and rankings, and order processing counting.

There are two types of Redis data expiration strategies: periodic deletion: periodic scan to delete the expired key, which can be set through expired-time-cap-remove-count and expired-time-cap-remove-delay parameters. Lazy Deletion: Check for deletion expired keys only when keys are read or written. They can be set through lazyfree-lazy-eviction, lazyfree-lazy-expire, lazyfree-lazy-user-del parameters.

In Debian systems, readdir system calls are used to read directory contents. If its performance is not good, try the following optimization strategy: Simplify the number of directory files: Split large directories into multiple small directories as much as possible, reducing the number of items processed per readdir call. Enable directory content caching: build a cache mechanism, update the cache regularly or when directory content changes, and reduce frequent calls to readdir. Memory caches (such as Memcached or Redis) or local caches (such as files or databases) can be considered. Adopt efficient data structure: If you implement directory traversal by yourself, select more efficient data structures (such as hash tables instead of linear search) to store and access directory information
