I've stumbled upon a Linus Torvalds' message regarding issue tracking that resonated with me (https://yarchive.net/comp/linux/bug_tracking.html):
> The thing is, bugzilla is totally broken because it's designed to help track bugs, but it's *not* designed to actually handle the much harder problem, which is to actually get the *right* developers to be aware of the *right* bugs! > > And both of those "right"s are important. Spamming everybody will just mean that everybody tunes them out. And spamming even the right developers with useless bugreports will also just cause them to tune out the good ones. Disclaimer: I gave up tracking all Druid issues about half a year ago, there is now too much noise for me there. I very occasionally visit my notifications on Github. I'm probably not alone. Please don't assume that just publishing PR is enough to let everybody know about it. @-mention people whose opinion you think may be important for an issue or a PR. Send a message to the dev mailing list for important issues/PRs. In general, it would be probably helpful to separate mailing lists for high-level things in Druid: ingestion/Kafka, querying, security/auth, approximate/sketches/complex aggregators stuff, SQL, coordination/segment balancing/ZK/discovery and setup bots that copy the right issues and PRs to the right lists based on tags.
