Freecache

freecache هي مكتبة تخزين مفتاح-قيمة عالية الأداء ومتزامنة في الذاكرة لتطبيقات Go. تعمل كذاكرة تخزين مؤقت ثابتة الحجم تدير كميات كبيرة من البيانات مع القضاء على عبء جمع القمامة (garbage collection) من خلال استخدام الذاكرة المخصصة مسبقاً والتخزين خارج الكومة (off-heap).

يحافظ النظام على بصمة ذاكرة يمكن التنبؤ بها من خلال استخدام تخصيص الذاكرة الثابت وإدارة المخزن المؤقت الدائري، حيث تقوم الإدخالات الجديدة تلقائياً بالكتابة فوق أقدم البيانات عند الوصول إلى السعة. كما يقلل من التنافس بين القراء والكتاب المتزامنين من خلال الوصول المتزامن المقفل.

تتضمن المكتبة واجهة خادم تنفذ مجموعة فرعية من بروتوكول Redis، مما يسمح للعملاء الخارجيين بالتواصل مع ذاكرة التخزين المؤقت باستخدام أوامر قياسية وخطوط أنابيب. تتم إدارة دورة حياة البيانات عبر انتهاء الصلاحية (time-to-live) وسياسات الإخلاء الآلي.

Features

Go In-Memory Caches - Provides a high-performance in-memory key-value store for Go applications designed to eliminate garbage collection pauses.
Cache Eviction Policies - Utilizes cache eviction policies based on expiration timestamps and LRU algorithms to maintain memory limits.
Concurrent Caches - Provides a thread-safe concurrent cache designed for high-concurrency environments with simultaneous reader and writer access.
Least Recently Used Caches - Implements a fixed-size cache that discards the oldest or least-recently-used entries when capacity limits are reached.
Circular Memory Buffers - Utilizes a circular memory buffer to automatically overwrite the oldest data when the fixed cache capacity is reached.
Off-Heap Memory Managers - Allocates data outside the managed heap to eliminate garbage collection overhead and prevent runtime pauses.
Slab Allocators - Uses slab allocators with fixed-size chunks to minimize memory fragmentation and ensure a predictable footprint.
Fixed Memory Buffers - Constrains memory usage to a preallocated fixed size to prevent application crashes and manage data via eviction.
Memory-Limited Caches - Implements memory-limited caching by capping the total byte size through strictly limited preallocated memory.
Lock-Striped Sharding - Employs lock-striped sharding to divide the data set and reduce contention among simultaneous readers and writers.
Concurrent Data Structures - Provides concurrent data structures that ensure thread-safe operations during simultaneous read and write access.
TTL Expiration Management - Provides TTL expiration management to automatically remove stale cache entries based on timestamps.
Redis Client Interfaces - Implements a Redis-compatible interface allowing external clients to communicate using standard Redis commands and pipelining.
Redis Protocol Parsers - Integrates a Redis protocol parser to allow external clients to communicate via standard Redis commands.
Protocol Servers - Implements a server interface that supports a subset of Redis commands and pipelining for external communication.
Time-To-Live Expirations - Implements time-to-live expirations to automatically remove stale cache entries and keep data current.
Caching Libraries - Zero-GC cache library.

Ristretto is a high-performance in-memory cache and concurrent key-value store for Go applications. It provides a thread-safe memory store that manages strict memory bounds and employs probabilistic set filters to reduce lookup overhead. The system is distinguished by an admission-policy cache that utilizes frequency sketches and cost-based eviction to maximize hit ratios. It minimizes contention and improves throughput through the use of striped ring buffers and concurrent map sharding. The project covers a broad range of data management capabilities, including time-based expiration, item f

node-lru-cache is a key-value store for Node.js that implements a memory-limited cache. It prevents memory exhaustion by capping the total number of items or total byte size, automatically evicting the least-recently-used items to maintain these limits. The project provides specialized caching patterns, including time-to-live durations to ensure data freshness and a stale-while-revalidate mechanism that serves expired content while asynchronously fetching updates in the background. It also includes diagnostic tools for monitoring cache hits, misses, and eviction metrics through operational st

This is a thread-safe in-memory cache library for Go that automatically evicts the least recently used items when capacity is reached. It provides a fixed-size memory cache designed to maintain a constant memory footprint by removing the oldest entries as new data arrives. The system includes an eviction manager that executes custom callbacks when entries are purged to facilitate resource cleanup. It also supports time-based expiration, allowing for the automatic removal of items after a specified time-to-live duration. The library covers general caching capabilities including cache inspecti

go-cache is a thread-safe, in-memory cache library for Go that stores arbitrary objects with per-item expiration timestamps. It provides a concurrent key-value store where multiple goroutines can safely read and write shared cached data without external synchronization, using a mutex-guarded map for access control. The library distinguishes itself through its expiration management and optional disk persistence. Each cached item carries its own time-to-live, and a background goroutine periodically purges expired entries. The cache can serialize its entire contents to disk using Go's gob encodi
