The official communication channels for Apache projects are their mailing lists, and Apache Beam has two main lists: user@beam.apache.org and dev@beam.apache.org. The topics for each of them can be seen in the section above.
Prior to sending emails to these lists, you need to subscribe. To subscribe, send a blank email to user-subscribe@beam.apache.org or dev-subscribe@beam.apache.org depending on the list you want to write to.
To unsubscribe, send a blank email to user-unsubscribe@beam.apache.org or dev-unsubscribe@beam.apache.org depending on the list you want to unsubscribe.
Tip 1: Use tags in your subject line. A tag is a word within a pair of brackets [] that indicate the type of message you’re sending. For example: [Bug] or [Proposal] or [Question] or [Idea]. Tags help folks navigate emails easier.
Tip 2: If you’re asking a troubleshooting question, provide as much information as possible to help others replicate your issue or find possible solutions.
Tip 3: Share complete links instead of hyperlinks. A common practice in Apache is adding a number tag like [1] to indicate a word is a link or an attachment, and use the tag as a footnote to add the complete link at the end of your message.
