gianm commented on issue #9111: Add HashJoinSegment, a virtual segment for joins. URL: https://github.com/apache/druid/pull/9111#issuecomment-569756152 > This is super cool thank you for putting this together. I would love to see a `README.md` (or similar) going over the high level mechanics of the join to help understand its limitations. I see a few comments scattered among classes but don't quite see the high level data flow. Is it all captured in #8728 , or are there more nuances in this PR since it is a foundation PR? @drcrallen -- #8728 is more of a program for starting to build join support than a description of mechanics. I agree that such a description of mechanics would be useful, although I haven't written it yet. I will start working on that and, maybe, it will outlive the proposal #8728 in usefulness. What sorts of questions would you want this mechanical description / design doc to answer?
