Overview

SecondLevelCache is an innovative caching library tailored for ActiveRecord, inspired by previous solutions like Cache Money and cache_fu, and supports versions 4 through 6 of ActiveRecord. With the complexities of modern applications demanding efficient data retrieval, this gem offers both write-through and read-through caching mechanisms, enhancing performance and ensuring consistency in data handling.

It simplifies database interactions by first checking the cache for requested data, which helps in minimizing direct database queries. If a cache miss occurs, SecondLevelCache intelligently populates the cache while ensuring that any updates or deletions to records automatically synchronize with the cached data. This approach not only optimizes performance but also maintains the integrity of your application's data.

Features

Read-Through Caching: Automatically checks the cache before querying the database, reducing unnecessary load and speeding up response times.
Write-Through Caching: Keeps all caches up-to-date automatically when records are created, updated, or deleted, ensuring data consistency.
Cache by Model Name and ID: Efficiently caches records based on unique identifiers, allowing for quick retrieval only for specific queries.
Custom Cache Prefixing: Easily change the cache_key_prefix to manage segmented cache calls, making it simple to handle various caching layers.
Supports Multiple ActiveRecord Versions: Works with ActiveRecord versions 4 to 6, making it versatile for different Rails applications.
Eager Loading Compatibility: Fully supports Rails's Eager Loading, enhancing query efficiency by transforming complex IN queries into swift multi-read operations.
Schema Digest Integration: Automatically expires caches when there are changes to the database schema, ensuring that cached data remains accurate and updated.
Optimized Cache Management: Employs strategies like Dalli for cache storage in production, enhancing performance and reliability.
