Apache Arrow Community
We welcome participation from everyone and encourage you to join us, ask questions, and get involved.
All participation in the Apache Arrow project is governed by the Apache Software Foundation’s code of conduct.
These arrow.apache.org mailing lists are for project discussion:
user@is for questions on using Apache Arrow libraries (subscribe, unsubscribe, archives)
dev@is for discussions about contributing to the project development (subscribe, unsubscribe, archives)
When emailing one of the lists, you may want to prefix the subject line with
one or more tags, like
[C++] why did this segfault?,
[Python] trouble with
wheels, etc., so that the appropriate people in the community notice the
You may also wish to subscribe to these lists, which capture some activity streams:
issues@for the creation of JIRA issues (subscribe, unsubscribe, archives)
commits@for commits to the apache/arrow and apache/arrow-site repositories (typically to
masteronly) (subscribe, unsubscribe, archives)
builds@for nightly build reports (subscribe, unsubscribe, archives)
In addition, we have some “firehose” lists, which exist so that development activity is captured in email form for archival purposes.
jira@for all activity on JIRA issues (subscribe, unsubscribe, archives)
github@for all activity on the GitHub repositories (subscribe, unsubscribe, archives)
For questions on how to use Arrow libraries, you may want to use the Stack Overflow tag apache-arrow in addition to the programming language. Some languages and subprojects may have their own tags (for example, pyarrow).
We support GitHub issues as a lightweight way to ask questions and engage with the Arrow developer community. That said, we use JIRA for maintaining a queue of development work and as the public record for work on the project, and we use the mailing lists for development discussions, so to keep things in a single place, we prefer not to have lengthy discussions on GitHub issues.
If you know your question is actually a bug report or feature request, we encourage you to go straight to JIRA. If you’re not sure, feel free to make a GitHub issue to ask your question and we can triage/redirect your question there.
