## What it is
JunoDB is PayPal's open-source secure, consistent, and highly available distributed key-value store delivering single-digit millisecond latency at any scale. It comprises storage servers, a proxy layer, and etcd-based cluster configuration, deployable via Docker.

## Use cases
- store key-value data with low single-digit millisecond latency
- run a secure distributed key-value database at any scale
- self-host a highly available NoSQL storage backend
- store session or user data with strong consistency
- deploy a scalable key-value store with Docker

## When to choose
- you need a highly available, consistent key-value store with low latency at scale
- you want a self-hosted alternative backed by PayPal's production experience
- security features like encryption and TLS are required for your storage layer

## When to avoid
- you need rich queries, joins, or SQL semantics rather than key-value access
- you want a turnkey managed database with minimal operational overhead
- your team cannot operate a multi-component distributed system (proxy, storage, etcd)

## Facets
- artifact type: service
- maturity: active
- function: database, security, caching
- domain: databases, microservices, backend, self-hosted
- platform: go, self-hosted
