The future of Flux

Flux is in maintenance mode and is not supported in InfluxDB v3 due to the broad demand for native SQL and the continued growth and adoption of InfluxQL.

InfluxData continues to support Flux for InfluxDB 1.x and 2.x, and you can continue using it without changing your code. If interested in transitioning to InfluxDB v3 and you want to future-proof your code, we suggest using InfluxQL.

As we developed InfluxDB v3, our top priority was improving performance at the database layer: faster ingestion, better compression, enhanced querying, and more scalability. However, this meant we couldn’t bring everything forward from v2. As InfluxDB v3 is a ground-up rewrite of the database in a new language (from Go to Rust), we couldn’t bring Flux forward to v3.

What do you mean by Flux is in maintenance mode?

We still support Flux, but are not actively developing any new Flux features. We will continue to provide security patches and will address any critical defects through the maintenance period. Our focus is our latest database engine, InfluxDB v3, and its associated products.

Is Flux going to End-of-Life?

No, we will continue to support Flux for the foreseeable future. We will continue to support our customers who have invested in Flux and have built apps that use it. You can continue using Flux, but if you want to future-proof your code, we recommend using InfluxQL or SQL.

What alternatives do you have for Flux tasks?

If moving to InfluxDB v3, you can’t bring Flux tasks because InfluxDB v3 doesn’t support Flux natively. When you move to v3, you will need to rewrite your tasks using whatever technologies your team prefers. However, if you’re using tasks for downsampling specifically, the storage performance in v3 is much better so you may no longer need tasks for this functionality.
