Act in Time.
Build on InfluxDB.
The platform for building time series applications.
新幸运飞行艇开奖官网 InfluxDB is the time series platform
Build real-time applications for analytics, IoT and cloud-native services in less time with less code using InfluxDB. At its heart is a database purpose-built to handle the epic volumes and countless sources of time-stamped data produced by sensors, applications and infrastructure. If time is relevant to your data, you need a time series database.
A powerful API and toolset for real-time applications
A high-performance time series engine
A massive community of cloud and open source developers
Trusted by developers from startups to Fortune 500 companies:
