We support GitHub issues as a lightweight way to ask questions and engage with the Arrow developer community. We use the Apache Software Foundation's JIRA instance for maintaining a queue of development work and as the public record for work on the project. So, feel free to delete this text and open an issue here if you have a question or aren't sure whether something is a bug or feature request. Any bugs, suggestions, or feature requests will eventually need to end up in JIRA, either before or after completing a pull request.
See the Arrow JIRA project here: https://issues.apache.org/jira/browse/ARROW.
For more in-depth development discussions, please use the public mailing list [email protected] (first subscribe by sending an e-mail to [email protected]).
