Project history

InfluxData documents Flux as a language that unifies querying, processing, writing, and acting on data in one syntax, with support for time-series databases, SQL databases, and CSV data sources.

The public Flux repository describes it as part of InfluxDB 1.7 and 2.0 while also runnable independently. InfluxData later placed Flux in maintenance mode and did not carry native Flux support into InfluxDB 3.

Adoption history

Flux adoption was tied to InfluxDB 1.7, InfluxDB 2.x, Flux tasks, dashboards, and the InfluxData documentation ecosystem. Its standard library grew broad support for data transformations, InfluxDB-specific operations, SQL, CSV, Prometheus-style functions, testing helpers, and notification endpoints.

InfluxData's current guidance says existing InfluxDB 1.x and 2.x users can continue using Flux, while new InfluxDB 3 work should generally use InfluxQL or SQL.

How it is used

Users write Flux scripts to read from buckets, filter and transform tables, join streams, aggregate windows, define functions, query external data sources, and drive tasks or alerts in InfluxDB-era workflows. The standalone flux command also exposes a REPL-style developer workflow in older releases.

Why package nerds care

Flux is notable to package maintainers because it is both a language runtime and a database-adjacent tool: packaging it means exposing a CLI, stdlib, parser, planner, and runtime outside the InfluxDB server that popularized it.

Its maintenance-mode status matters for curation because the package remains useful for legacy InfluxDB 1.x/2.x users even though InfluxDB 3 moved toward SQL and InfluxQL.

Timeline

• 2018: Flux v0.7.x releases were published during early language development.
• 2018: Flux v0.14.0 changed the flux command into a REPL and organized built-in code into Flux packages.
• 2019: Flux v0.65.0 was published during the pre-1.0 language series.
• 2020: InfluxDB 2.0-era adoption made Flux central to many InfluxData 2.x workflows.
• 2026: InfluxData documentation states that Flux is in maintenance mode and not supported in InfluxDB 3.

Related projects

• InfluxDB 1.x, InfluxDB 2.x, InfluxDB 3, InfluxQL, SQL, Telegraf, Chronograf, and Kapacitor are closely related parts of the InfluxData ecosystem.
• Prometheus, SQL databases, and CSV sources are important integration targets documented in the Flux standard library and query-source docs.
