Cache - standardize PHP data caching

This is a PHP library providing standardized interfaces for caching data through the PSR-6 and PSR-16 specifications. It functions as a cache pool manager and distributed cache adapter, allowing applications to organize key-value pairs into logical repositories and namespaces.

The project includes a dedicated cache stampede prevention tool that protects systems from CPU spikes during value expiration. This is achieved through locking mechanisms for concurrent requests and probabilistic early expiration.

The library supports object serialization with optional encryption and compression to translate complex data into storable formats. It provides a multi-backend storage abstraction layer, enabling data persistence across memory, filesystems, and distributed databases. Other capabilities include callback-based cache retrieval and key-based namespacing for data segregation.

Features

Caching Interfaces - Provides a full implementation of standardized PHP-FIG caching interfaces (PSR-6 and PSR-16) for library interoperability.
Distributed Caching - Manages shared state across multiple servers using adapters for distributed databases and filesystems.
Cache Pool Organization - Organizes cached key-value pairs into logical repositories and namespaces to provide a structured data storage system.
Multi-Backend Storage Management - Implements a unified API to coordinate and manage cached data across diverse storage engines like memory, filesystems, and distributed databases.

Simple Cache is a technical specification and interface standard for PHP applications. It defines a common set of methods for interacting with cache storage, ensuring that different storage implementations can be used interchangeably. As the PSR-16 implementation standard, it provides a consistent way for independent PHP libraries and frameworks to store and retrieve cached data. This interoperability allows software packages to work with any compliant cache backend without requiring changes to the application code. The specification focuses on standardizing cache interfaces and interactions

memcached/memcached

Memcached is a high-performance, distributed, in-memory key-value storage and request routing engine. It functions as a volatile data store designed to accelerate dynamic applications by caching objects in RAM, thereby reducing backend database load and providing sub-millisecond response times. The system utilizes a specialized architecture that organizes memory into fixed-size slabs to minimize fragmentation and maximize throughput for high-concurrency workloads. The project distinguishes itself through a multi-threaded, lock-friendly design that scales across CPU cores and supports complex

LanceDB is a vector database and columnar data store designed to function as a versioned dataset manager and vector search engine. It serves as a high-performance backend for indexing and retrieving high-dimensional embeddings, providing the foundation for machine learning data pipelines. The system distinguishes itself through a combination of cloud-native object storage and immutable version tracking, allowing for data time-travel and reproducible AI experiments. It integrates hybrid search capabilities, merging dense vector similarity with BM25 full-text search and SQL-like scalar filters

LMCache/LMCache

LMCache is a distributed key-value cache manager and tiering system designed to accelerate large language model inference. It functions as a tiered storage layer that offloads tensors from GPU memory to CPU RAM, local disks, or remote object stores, enabling the reuse of cached prefixes across different inference sessions and serving engines. The system differentiates itself through a disaggregated prefill-decode model, which separates prompt processing from token generation by transferring caches between distributed compute nodes. It utilizes peer-to-peer orchestration to share and retrieve
