## What it is
Nebulex is an in-memory and distributed caching toolkit for Elixir that provides a cache abstraction layer similar to Ecto's database abstraction. It supports multiple cache backends via adapters (Redis, Memcached, local caches) and offers declarative decorator-based caching, cache usage patterns, and distributed cache topologies.

## Use cases
- add caching to an existing Elixir application transparently
- set up a distributed cache across Elixir nodes
- cache Ecto query results declaratively with decorators
- swap cache backends like Redis or Memcached without changing application code
- implement cache-aside and read-through patterns in Elixir
- build a generational local in-memory cache

## When to choose
- you are building an Elixir application and need a flexible caching abstraction with pluggable adapters
- you need distributed cache topologies or declarative caching decorators
- you want an Ecto-like consistent API across different cache implementations

## When to avoid
- you need a simple standalone key-value store without an abstraction layer
- your project is not in the Elixir/BEAM ecosystem
- you need a cache server itself rather than a client-side caching framework

## Facets
