How to choose mongodb and redis
Choose MongoDB or Redis according to application requirements: MongoDB is suitable for storing complex data, and Redis is suitable for fast access to key-value pairs and caches. MongoDB uses document data models, provides persistent storage and horizontal scalability; while Redis uses key values to perform well and cost-effectively. The final choice depends on the specific needs of the application, such as data type, performance requirements, scalability, and reliability.
MongoDB and Redis selection
MongoDB and Redis are two popular choices when choosing database technology. Choosing the right database depends on the specific needs of the application.
use
- MongoDB: Document-oriented database for storing complex structured data such as user accounts and product catalogs.
- Redis: Memory data structure storage, suitable for storing fast access key-value pairs and caches.
Data Model
- MongoDB: Using the document data model, you can store complex and nested data structures.
- Redis: Use key-value pair data model, each piece of data consists of keys and values.
performance
- MongoDB: Good performance for complex queries and aggregation operations.
- Redis: Performance is excellent for fast read and write operations because it stores data in memory.
Scalability
- MongoDB: Can scale horizontally to multiple nodes, thereby increasing throughput.
- Redis: Scalability can be achieved by using clustering or sharding technology.
reliability
- MongoDB: Provides persistent storage and replication functions to ensure data reliability.
- Redis: By default, persistent storage is not provided, and data reliability needs to be ensured by enabling persistence mechanism.
Other considerations
- Cost: Redis is generally more cost-effective than MongoDB.
- Ease of use: MongoDB provides a more complex data model, while Redis provides a simpler key-value pair model.
- Support: Both platforms offer comprehensive documentation and community support.
Selection Guide
- Need to store complex and nested data: MongoDB
- Requires quick read and write operations: Redis
- Need to extend horizontally: MongoDB
- ต้องการ Cost-effective solution: Redis
- Persistent storage required: MongoDB
By considering these factors, you can make an informed choice between MongoDB and Redis based on the specific needs of your application.

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)

When developing an e-commerce website, I encountered a difficult problem: how to provide users with personalized product recommendations. Initially, I tried some simple recommendation algorithms, but the results were not ideal, and user satisfaction was also affected. In order to improve the accuracy and efficiency of the recommendation system, I decided to adopt a more professional solution. Finally, I installed andres-montanez/recommendations-bundle through Composer, which not only solved my problem, but also greatly improved the performance of the recommendation system. You can learn composer through the following address:

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

Use the JSON Viewer plug-in in Notepad to easily format JSON files: Open a JSON file. Install and enable the JSON Viewer plug-in. Go to "Plugins" > "JSON Viewer" > "Format JSON". Customize indentation, branching, and sorting settings. Apply formatting to improve readability and understanding, thus simplifying processing and editing of JSON data.

Detailed explanation of MongoDB efficient backup strategy under CentOS system This article will introduce in detail the various strategies for implementing MongoDB backup on CentOS system to ensure data security and business continuity. We will cover manual backups, timed backups, automated script backups, and backup methods in Docker container environments, and provide best practices for backup file management. Manual backup: Use the mongodump command to perform manual full backup, for example: mongodump-hlocalhost:27017-u username-p password-d database name-o/backup directory This command will export the data and metadata of the specified database to the specified backup directory.

Enable Redis slow query logs on CentOS system to improve performance diagnostic efficiency. The following steps will guide you through the configuration: Step 1: Locate and edit the Redis configuration file First, find the Redis configuration file, usually located in /etc/redis/redis.conf. Open the configuration file with the following command: sudovi/etc/redis/redis.conf Step 2: Adjust the slow query log parameters in the configuration file, find and modify the following parameters: #slow query threshold (ms)slowlog-log-slower-than10000#Maximum number of entries for slow query log slowlog-max-len
