## Health v2 (maintenance only)
Score: 94/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 99, release rhythm 84, longevity 100
- inputs: {"age_days": 4485, "days_push": 7, "days_rel": 28, "gap_med": 83, "n_releases_24m": 10}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Apache HBase is an open-source, distributed, versioned, column-oriented NoSQL database modeled after Google Bigtable, running on top of Apache Hadoop and HDFS. It provides random, real-time read/write access to billions of rows and millions of columns with strong consistency, automatic sharding, and failover.

## Use cases
- store billions of rows with random real-time read/write access
- ingest high-volume time-series and metrics data
- store IoT device telemetry at scale
- serve low-latency user profiles and counters for ad tech
- store immutable message and audit logs with efficient range scans
- run large sparse columnar datasets for genomics research

## When to choose
- you need linearly scalable, strongly consistent random access on commodity clusters
- your workload is high-ingest, append-mostly like time-series or logs
- you already run Hadoop/HDFS and want Bigtable-like storage
- you need sparse wide tables with millions of columns

## When to avoid
- you need ad-hoc SQL, joins, or relational constraints
- your dataset fits comfortably in a single relational database
- you lack operational capacity to run a distributed cluster with ZooKeeper
- you need simple document storage without schema design effort

## Facets
- artifact type: service
- maturity: stable
- function: database, search-engine, monitoring, tracing
- domain: databases, big-data, microservices, analytics
- platform: jvm, cloud, self-hosted
- tags: nosql, column-oriented, bigtable, hadoop, wide-column-store, time-series, hdfs, real-time-read-write, data-engineering, linux, docker
