## What it is
Moneta is a Ruby library providing a unified interface to many key/value stores, including NoSQL and document databases. It supports configurable serialization, compression, and expiration via a proxy stack, plus atomic operations and distributed synchronization primitives.

## Use cases
- swap key/value backends without changing application code
- add caching to a Rails or Sinatra app with a pluggable store
- benchmark and compare different key/value stores
- add TTL/expiration to stores that lack native support
- implement distributed locks with Moneta::Mutex
- serialize and compress values transparently across backends

## When to choose
- you need one consistent API over multiple key/value stores in Ruby
- you want swappable cache or session stores across frameworks
- you need atomic increments or distributed mutexes on top of a KV store

## When to avoid
- you use a non-Ruby language
- you need advanced store-specific features not exposed by the unified API
- you need a full-featured ORM or document query layer

## Facets
- artifact type: library
- maturity: stable
- function: database, caching, serialization, compression, middleware
- domain: databases, developer-tools, web-development, backend
- platform: ruby, cross-platform
- tags: key-value-store, nosql, cache-store, abstraction-layer, rack, rails
