[ Ruby on Rails ] Ruby 與 Redis 整合之相關資源整理

一年多前Ruby和Redis整合資源沒這麼豐富的時候,我寫了一篇 [ Ruby on Rails ] Redis相關Gem介紹了一些當下僅有的Gem,但事隔一年多,Redis的資源越來越多,手邊也蒐集了一些觀察及使用名單,也許不全都屬於Ruby,但相信對Ruby的使用者來說應該不是什麼問題。之前介紹的基本上大同小異我就不再贅述,這篇文章會把近一年來實用或是出名的工具做一些整理以及基本的介紹,如果在這份名單裡面有你愛用的工具而我沒推薦到的也歡迎提供! Integrate with Ruby( Rails ) nest 非常適合提高Redis和Rails整合維護性的Gem,可以把Ruby的Hash自動整合成Redis的key!整合方式可參考 Redis Application Patterns In Rails 。 redis-namespace 和nest類似的東西,但個人比較喜歡nest。 redis_props 類似 redis-objects 的Gem,但使用上更單純簡單一點。 ohm 類似 redis-objects 的Gem,但和redis-objects有一樣的問題,Redis原生的指令就已經很好用了,他卻改變原本應有的操作方式,對於這類型Gem我沒有太多興趣。 redis-store 非常棒的一個Gem,可以把Redis當Memcached一樣整合到Rails的Cache ,如果不想一邊維護Redis一邊維護Memcached可以考慮使用他。 Search & AutoComplete redis-textsearch 不錯的一個Gem,但斷詞系統是以英文為主,不支援中文。 redis-search 由對岸高手開發的Redis … 繼續閱讀

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
