## Health v2 (maintenance only)
Score: 77/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 99, release rhythm 35, longevity 100
- inputs: {"age_days": 4213, "days_push": 7, "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
Apache Ignite is a distributed, memory-first database with in-memory speed, ACID transactions, and SQL support across a cluster. It can serve as a caching layer, key-value store, or full database with native persistence and distributed computing capabilities.

## Use cases
- speed up reads with an in-memory cache in front of a slow database
- run distributed SQL queries across a cluster
- store microservices state and session data
- process event streams in real time
- build an AI/ML feature store
- handle IoT and time-series data at scale
- run ACID transactions spanning multiple servers
- perform high-performance distributed computing

## When to choose
- you need low-latency, in-memory data access at scale
- you want a distributed SQL database with ACID guarantees
- you need a caching layer plus native persistence in one system
- your workload involves real-time analytics, IoT, or event streaming

## When to avoid
- you need a simple embedded database for a single-node app
- your dataset is small and a traditional RDBMS suffices
- you cannot operate a JVM-based cluster or manage distributed infrastructure
- you want a lightweight key-value store without clustering overhead

## Facets
- artifact type: application
- maturity: stable
- function: database, caching, search-engine, streaming, concurrency
- domain: databases, big-data, microservices, iot, cloud-computing
- platform: jvm, windows, cross-platform
- tags: in-memory-computing, distributed-sql, key-value-store, acid-transactions, hadoop, data-grid, compute-grid, java, apache, real-time, linux, macos, docker
