## What it is
fastapi-cache is a Python library that adds caching to FastAPI endpoints and function results via a simple @cache decorator. It supports Redis, Memcached, Amazon DynamoDB, and in-memory backends, plus HTTP cache headers like ETag and Cache-Control.

## Use cases
- cache fastapi endpoint responses
- cache function results in fastapi
- add redis caching to fastapi app
- serve cached responses with etag headers
- speed up slow api endpoints with caching
- cache api responses in memcached

## When to choose
- you use FastAPI and want drop-in response or function caching
- you need pluggable cache backends like Redis, Memcached, or DynamoDB
- you want HTTP-level caching semantics like ETag and Cache-Control

## When to avoid
- you use Flask, Django, or another non-FastAPI framework
- you need distributed cache invalidation or advanced cache strategies beyond TTL
- your app is not async or does not use FastAPI

## Facets
