help InfluxData InfluxDB FAQ
What is InfluxDB used for?
InfluxDB is a time-series database designed for data that changes over time, such as metrics, sensor readings, and system measurements. Common use cases include monitoring, IoT, and operational analytics.
What are retention policies in InfluxDB?
Retention policies define how long time-series data should be kept and can help control storage growth. For example, a team might retain high-resolution monitoring data for a shorter period and keep summarized data longer.
What query language does InfluxDB use?
The catalog description identifies Flux as an InfluxDB query language. InfluxDB deployments and versions have differed in their query-language support, so users should check the version before designing a new query layer.
Why choose InfluxDB instead of a general relational database?
InfluxDB is purpose-built for high-volume, high-velocity time-series streams and provides time-oriented functions such as aggregation and retention handling. A relational database may still be a better fit for transactional records with complex relationships.
