I am submitting my candidacy for Swift PTL for the Newton cycle. ### Community growth During the Mitaka cycle, we've seen the community grow from about 440 contributors to 531 today. That's a 20% growth in the last six months. This growth rate is huge, and I'm really happy to see all the new people coming into the community. New contributors bring new ideas, new use cases, and fresh eyes on old problems. This is the hallmark of a healthy community. New contributors reflect the broader picture of what's going on with Swift, too. When we see new contributors from companies who are already actively participating in the community, it shows that they are using Swift more. When new companies join the community for the first time, it shows new places where Swift is being used to solve real-world storage problems. Both situations are exciting. Swift is growing. More people are using it to store more data and solve more storage problems. As I've said many times before, my vision for Swift is that it will be used by everyone, every day, even if people don't realize it. Community growth is one way we can see that this is happening today. ### Tracking the community One thing I've been working on over the last year is tracking our community and finding ways to understand it and help it continue to grow. You can see some of this work in the graphs below. http://d.not.mn/total_contribs.png http://d.not.mn/active_contribs.png I've been working on a few more interesting graphs and metrics too. I've shared one of these before: visualizing individual contributor activity over time. You can see the results at http://d.not.mn/contrib_activity.png. This is a rather large graph, but it's fairly simple to read. The x-axis is time (from Swift's initial release to today). Each line on the y-axis is a person's activity in Swift. Blue boxes are for authoring a patch; green boxes are for a review. This graph has been invaluable in helping understand who is contributing to the project and what activity active contributors are engaged in. One thing I've learned is that there is a class of contributor who has been involved for a long time, but is only active infrequently. Most of these people are operators who are normally running production clusters but occasionally need to submit a patch or review upstream. Another thing I've worked on is a way to find out what the community as a whole thinks is important. We can start to find a lot of this info from information we already have. For example, we can get a list of every patch that every contributor has starred to see if there is any commonality between them. The patches that are more often starred are likely to be more important, from the community perspective. I've taken that basic idea, along with some further parsing of information from gerrit, and created a review dashboard. It's going to keep changing, but you can see its current incarnation at http://not.mn/swift/swift_community_dashboard.html (and linked in the #openstack-swift channel topic). So far, I've seen this dashboard result in a dramatic decrease in the number of unreviewed patches, and as the dashboard improves, I expect it to lead to a similar improvement in review times for important patches. ### Current struggles Tracking the community (both with metrics like above and from simply talking to people) shines a light on common problems in the community. Two of the most-often raised issues are that of long patch review times and review prioritization. We've been improving both of these with several tools in the past, and we're currently in a much better place than we've been in the past. As PTL, I feel it's my duty to enable the community to solve these problems. I will continue to improve the tools we have and create new tools as necessary so that we know what's going on, what to work on, and make every contributor effective. ### Goals for newton Looking forward to the Newton cycle, I want to see three things happen. 1. Increased contributor growth 2. Progress on significant code efforts, including crypto, improved global clusters, and improved performance 3. Better tools and info for community prioritization and community tracking The community is well-positioned to meet these goals, and I will be honored to continue to serve you as PTL for OpenStack Swift.
