## What it is
Apache Curator is a high-level Java/JVM client library for Apache ZooKeeper, a distributed coordination service. It provides a simplified API framework, reliability utilities, common recipes like distributed locks and leader election, service discovery, and a Java 8 asynchronous DSL.

## Use cases
- manage ZooKeeper connections with retry and reliability handling
- implement distributed locks and leader election
- discover services registered in ZooKeeper
- build distributed coordination primitives like barriers and queues
- use an async DSL for ZooKeeper operations

## When to choose
- you use ZooKeeper from Java/JVM and want a reliable high-level client
- you need battle-tested distributed coordination recipes
- you want service discovery backed by ZooKeeper

## When to avoid
- you don't use ZooKeeper
- you need a non-JVM client
- you want coordination without running a ZooKeeper ensemble

## Facets
- artifact type: library
- maturity: stable
- function: database-driver, middleware, concurrency, service-discovery, sdk
- domain: microservices, developer-tools, databases
- platform: jvm
- tags: zookeeper, coordination, distributed-locking, recipes, java
