CacheSysteme

CacheSysteme is a caching subsystem designed to improve data retrieval performance by storing frequently accessed objects in a fast storage tier. It is designed to be language-agnostic and can operate as an in-process library, a standalone service, or a distributed cache cluster. CacheSysteme provides APIs to read and write cached values, configure expiration, and attach invalidation hooks.

The architecture comprises a cache store, a cache manager, and a pluggable eviction policy module. The cache store holds serialized data and metadata such as TTL, size, and last access time. The cache manager coordinates read and write operations, enforces eviction when capacity is reached, and handles cache coherency across distributed instances via invalidation messages or pub/sub channels. Adapters allow the system to use memory, on-disk storage, or external backends like Redis or Memcached, with optional hybrid layouts.

Data in CacheSysteme is modeled as key-value pairs, optionally accompanied by metadata such as version, tags, or dependency references. Serialization formats can be configured (binary, JSON, etc.). TTL-based expiration and eviction policies such as Least Recently Used, Least Frequently Used, or custom policies govern replacement. In distributed deployments, features include cache sharding, time-based invalidation, and coherence guarantees calibrated to application needs.

Typical use cases include web application response caching, database query result caching, and API result caching to reduce backend load and latency. The advantages include reduced latency and load, while trade-offs involve memory consumption, serialization overhead, and potential staleness if invalidation is not timely. CacheSysteme is often compared with established caching layers such as in-process caches, distributed caches, and content delivery caches.
