Query and code together with Flux

A powerful language from the makers of InfluxDB that allows developers to see across time.

What is Flux?

Flux is a standalone data scripting and query language that increases productivity and code reuse.

Flux is optimized for ETL, monitoring, and alerting, with an inline planner and optimizer.

Flux is the result of the open source community driving innovation with time series data.


Why use Flux?

  • 001-triangle-hl

    Flux is fun:

    Flux is easy to learn and highly productive, with great readability. Flux has a command line interface and a web-based UI for point-and-click scripts.

  • Flux-fullW-hl-2

    Flux is productive:

    Flux is composable. Developers can build on top of the language for specific use cases. You can include other Flux modules in the code and contribute new functions to the platform.

    Since Flux queries are code, they can be tested and checked into source control systems. Parts of queries can be tested in isolation, and complex queries can be built from separately tested sub-components.

  • dev-doc-hl-icon

    Flux supports multiple data sources:

    The ability to integrate with other systems is a core design feature of Flux. Integrate disparate data sources, including databases, third-party APIs or filesystems anywhere data lives.

  • network-hl

    Flux is extensible:

    New contributors of Flux functions and libraries can engage easily without knowing all the internals. Join our marketplace of industry-specific functions like dollar-cost averaging and dwell-time provisioning.

  • cloud-network-hl

    Flux lets you cross-compile:

    Work on top of Flux with other syntax like PromQL, InfluxQL, and others. Flux works on a single optimizer that plans against different sources.

  • data-hl

    Flux integrates with your tools:

    Flux plays nice with analytics tools and environments like Jupyter and uses the Apache Arrow data interchange format to speed integration with big data analytics systems.

    Learn more about the design goals of Flux and why it was developed in the first place.

“Flux is much more flexible because it is not just a query language... The ability to combine data from different sources is great.”
