How to use Redis and TypeScript to develop high-performance computing functions
Overview:
Redis is an open source in-memory data structure storage system that is high-performance and scalable sexual characteristics. TypeScript is a superset of JavaScript that provides a type system and better development tool support. Combining Redis and TypeScript, we can develop efficient computing functions to process large data sets and make full use of Redis's memory storage and computing capabilities.
This article will introduce how to use Redis and TypeScript to develop high-performance computing functions, including data storage, data processing, and result caching. We will use common data structures and commands of Redis and provide specific code examples.
- Data Storage
First, we need to store the data that needs to be calculated into Redis. Redis provides a variety of data structures, and you can choose the appropriate data structure to store data according to specific needs. Commonly used data structures include String, List, Set, Sorted Set, etc.
For example, we can store the data that needs to be calculated as a list:
import * as Redis from 'ioredis'; const client = new Redis(); // 存储数据到列表中 async function appendDataToList(data: number[]): Promise<void> { await client.rpush('dataList', ...data.map(String)); }
- Data processing
Once the data is stored in Redis, we can perform operations on the data Handle accordingly. Using the commands and data structures provided by Redis, we can implement various calculation functions, such as summation, maximum value, sorting, etc.
For example, we can perform a sum operation on data stored in a list:
import * as Redis from 'ioredis'; const client = new Redis(); // 计算列表中数据的和 async function sumDataInList(): Promise<number> { const values = await client.lrange('dataList', 0, -1); return values.reduce((sum: number, value: string) => sum + parseInt(value), 0); }
- Result cache
In order to improve calculation performance, we can Cache it for subsequent repeated calculations. The caching function of Redis can help us quickly obtain previously calculated results.
For example, we can store the summation results in the cache of Redis:
import * as Redis from 'ioredis'; const client = new Redis(); // 存储结果到缓存中 async function cacheResult(key: string, result: number): Promise<void> { await client.set(key, String(result)); } // 从缓存中获取结果 async function getCachedResult(key: string): Promise<number | null> { const result = await client.get(key); if (result === null) { return null; } return parseInt(result); }
Using the above technology comprehensively, we can store the data in Redis and calculate the data, And cache the calculation results to improve calculation performance and reusability.
The sample code uses the Node.js library ioredis
to connect and operate Redis. You can use other appropriate libraries according to your own development environment and needs.
Summary:
In big data processing and high-performance computing scenarios, the combination of Redis and TypeScript can provide good performance and development experience. By rationally selecting data structures and utilizing the caching features of Redis, we can achieve efficient data storage and computing functions. At the same time, TypeScript’s type system and tool support can reduce development errors and improve code maintainability.
The above is a brief introduction on how to use Redis and TypeScript to develop high-performance computing functions. I hope it will be helpful to you. In actual development, please adjust and optimize according to specific needs and environment.

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.

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.

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.

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
