OpenTSDB Review
Distributed time series database built on HBase/Hadoop that stores and serves massive volumes of metrics with millisecond precision at millions of writes per second.
Verdict
OpenTSDB is a proven, horizontally scalable metrics store used by large engineering teams that already operate Hadoop/HBase infrastructure and need to retain raw time series data indefinitely without downsampling. It integrates with open-source frontends and exposes an HTTP API for querying. The hard dependency on Hadoop/HBase makes it a poor fit for smaller teams, and its last release (2.4.1, 2021) signals a slow development pace relative to newer TSDB alternatives like InfluxDB or VictoriaMetrics.
