A time-series database (TSDB) is a specialized database optimized for storing, querying, and analyzing time-stamped or time-ordered data such as metrics, events, and sensor readings. It matters because it can efficiently handle very high write rates, long retention periods, and time-based aggregations that are common in observability, IoT, and financial applications.
Popular open-source and commercial TSDB with its own query languages (InfluxQL, Flux) and a full observability platform.
PostgreSQL extension that adds time-series capabilities while retaining full SQL and PostgreSQL ecosystem compatibility.
Open-source monitoring system and TSDB focused on metrics collection and alerting for cloud-native environments.
Fully managed time-series database service on AWS with built-in tiered storage and integrations with AWS analytics tools.
