## What it is
OpenTSDB is a distributed, scalable time series database (TSDB) built on top of HBase, written in Java. It stores, indexes, and serves metrics collected from computer systems at massive scale, keeping raw data forever with millisecond precision.

## Use cases
- store infrastructure metrics from tens of thousands of hosts
- collect and query application monitoring metrics at high write rates
- graph server and network equipment metrics over time
- keep raw time series data forever without downsampling
- query metrics via an HTTP API for dashboards
- scale time series storage horizontally by adding HBase nodes

## When to choose
- you already run Hadoop/HBase infrastructure and need large-scale metrics storage
- you need to store hundreds of billions of data points without losing granularity
- you want a proven, mature TSDB with an HTTP API and GUI
- you need multi-datacenter replication via HBase

## When to avoid
- you want a simple single-node time series database without HBase dependencies
- you need a lightweight metrics store for small projects
- you prefer modern TSDBs like Prometheus, InfluxDB, or VictoriaMetrics with easier operations
- your team cannot operate a JVM/HBase stack

## Facets
- artifact type: service
- maturity: maintenance
- function: database, monitoring, analytics, http-server
- domain: databases, monitoring, big-data, analytics
- platform: jvm, self-hosted
- tags: time-series-database, hbase, metrics, distributed, monitoring, devops, linux, docker
