Communication

We welcome participation from everyone and encourage you to join us, ask questions, and get involved.

All participation in the Apache DataFusion project is governed by the Apache Software Foundation’s code of conduct.

GitHub

The vast majority of communication occurs in the open on our github repository in the form of tickets, issues, discussions, and Pull Requests.

Slack and Discord

We use the Slack and Discord platforms for informal discussions and coordination. These are great places to meet other contributors and get guidance on where to contribute. It is important to note that any technical designs and decisions are made fully in the open, on GitHub.

Most of us use the ASF Slack workspace and the Arrow Rust Discord server for discussions.

There are specific channels for Arrow, DataFusion, and the DataFusion subprojects (Ballista, Comet, Python, etc).

In Slack we use these channels:

  • #arrow

  • #arrow-rust

  • #datafusion

  • #datafusion-ballista

  • #datafusion-comet

  • #datafusion-python

In Discord we use these channels:

  • #ballista

  • #comet

  • #contrib-federation

  • #datafusion

  • #datafusion-python

  • #dolomite-optimizer

  • #general

  • #hiring

  • #incremental-materialized-views

Unfortunately, due to spammers, the ASF Slack workspace requires an invitation to join. We are happy to invite you – please ask for an invitation in the Discord server.

Mailing Lists

Like other Apache projects, we use mailing lists for certain purposes, most importantly release coordination. Other than the release process, most DataFusion mailing list traffic will simply link to a GitHub issue or PR where the actual discussion occurs. The project mailing lists are:

  • dev@datafusion.apache.org: the main mailing list for release coordination and other project-wide discussions. Links: archives, subscribe, unsubscribe

  • github@datafusion.apache.org: read-only mailing list that receives all GitHub notifications for the project. Links: archives

  • commits@datafusion.apache.org: read-only mailing list that receives all GitHub commits for the project. Links: archives

  • private@datafusion.apache.org: private mailing list for PMC members. This list has very little traffic, almost exclusively discussions on growing the committer and PMC membership. Links: archives
