## What it is
cache2go is a concurrency-safe, in-memory caching library for Go with per-item expiration (TTL) and access counters. It supports arbitrary key/value types, deletion callbacks, and multiple named cache tables.

## Use cases
- cache expensive function results in memory with a TTL
- add a concurrency-safe key-value cache to a Go service
- expire cached items after a period of inactivity
- track how often cached entries are accessed
- run callbacks when cached items are deleted

## When to choose
- you need a simple, dependency-free in-process cache in Go
- you want per-item TTLs based on last access time
- you need arbitrary Go types as keys and values

## When to avoid
- you need a distributed or shared cache across processes (use Redis or Memcached)
- you need size-bounded eviction like LRU
- you need persistence for cached data

## Facets
- artifact type: library
- maturity: stable
- function: caching, concurrency
- domain: developer-tools, backend, performance
- platform: go, cross-platform
- tags: in-memory-cache, expiration, ttl, access-counters, callbacks
