## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 5615, "days_push": 3822, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Doozer is a highly-available, fully consistent distributed data store for small amounts of critical in-memory data, built on a consensus algorithm with no single leader. Clients can GET, SET, and WATCH keys and receive immediate notifications when data changes.

## Use cases
- service discovery and name service for changing machine addresses
- database master election and failover coordination
- sharing configuration data across machines with real-time updates
- watching keys for changes without polling
- storing small amounts of critical metadata in a distributed cluster

## When to choose
- you need strongly consistent, highly-available storage for small in-memory data
- clients must be notified immediately when shared data changes
- you need leader election or name service functionality across machines

## When to avoid
- you need durable on-disk storage or large datasets
- you need an actively maintained project - the latest release is from 2016
- you only need simple caching or eventual consistency

## Facets
- artifact type: service
- maturity: abandoned
- function: database, message-queue, configuration-management, service-discovery
- domain: microservices, databases, infrastructure-as-code
- platform: go, cli, self-hosted
- tags: distributed-consensus, key-value-store, coordination-service, real-time-updates, high-availability, devops, linux, macos
