## What it is
A generic connection pooling library for Ruby that manages a shared pool of objects (network clients, connections) across threads and fibers. It provides blocking checkout with timeouts, a wrapper for easy migration, and shutdown/reload lifecycle support.

## Use cases
- pool redis connections across threads in ruby
- share a memcached client among fibers
- limit concurrent connections to a network service
- migrate a global connection to a pool gradually
- fail fast when pooled resources are exhausted
- pool any ruby client object, not just databases

## When to choose
- you need to share limited connections (redis, memcached, http clients) across threads or fibers
- your client library lacks its own pooling
- you want timeout-based backpressure when the pool is exhausted

## When to avoid
- your ORM or client (ActiveRecord, MongoDB driver) already provides its own pool
- you need pooling in a language other than ruby

## Facets
- artifact type: library
- maturity: stable
- function: concurrency, database-driver, developer-tools
- domain: developer-tools, backend, databases, performance
- platform: ruby
- tags: connection-pooling, threading, fibers, redis, memcached
