Score: 32/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 5308, "days_push": 835, "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
HyperDex is a distributed, searchable, and consistent key-value store written in C++. It provides scalable storage with secondary-index search capabilities across a cluster.

## Use cases
- run a scalable distributed key-value store
- search key-value data by secondary attributes
- store data with strong consistency across a cluster
- deploy a searchable nosql database
- query stored values beyond primary key lookups

## When to choose
- you need a distributed KV store with secondary-index search
- you want consistent, scalable storage self-hosted on Linux

## When to avoid
- you need a managed cloud database
- your workload is small enough for a single-node store
- you need rich ecosystem support or frequent updates

## Facets
- artifact type: service
- maturity: maintenance
- function: database, search-engine, caching
- domain: databases, microservices, backend
- platform: cpp, self-hosted
- tags: key-value-store, distributed-storage, searchable-kv, search, linux
