For all Apache projects, mailing lists are the source of truth. See: "If it didn't happen on a mailing list, it didn't happen." https://community.apache.org/newbiefaq.html#is-there-a-code-of-conduct-for-apache-projects <https://community.apache.org/newbiefaq.html#is-there-a-code-of-conduct-for-apache-projects>
In response to Jason’s question, here are two things I’ve seen work well in the Apache Mesos community: 1. I’d suggest setting up an iss...@cassandra.apache.org mailing list which posts all changes to JIRA tickets (comments, issue reassignments, status changes). This could be subscribed to like any other mailing list, and while this list would be high volume it increases transparency of what’s happening across the project. For Apache Mesos, we have a issues@mesos list: https://lists.apache.org/list.html?iss...@mesos.apache.org <https://lists.apache.org/list.html?iss...@mesos.apache.org> for this purpose. It can be hugely valuable for keeping tabs on what’s happening in the project. If there’s interest in creating this for Cassandra, here’s a link to the original INFRA ticket as a reference: https://issues.apache.org/jira/browse/INFRA-7971 <https://issues.apache.org/jira/browse/INFRA-7971> 2. Apache Mesos has formalized process of design documents / feature development, to encourage community discussion prior to being committed — this discussion takes place on the mailing list and often has less to do with the merits of a particular patch as much as it does on an overall design, its relationship to dependencies, its usage, or larger issues about the direction of a feature. These discussions belong on the mailing list. To keep these discussions / design documents connected to JIRA we attach links to JIRA issues. For example: https://cwiki.apache.org/confluence/display/MESOS/Design+docs+--+Shared+Links <https://cwiki.apache.org/confluence/display/MESOS/Design+docs+--+Shared+Links>. The design doc approach is more of a formalization of what Jonathan originally proposed.
