The rabbit reflects on Trino in 2022

10 Jan 2023 | Brian Olsen, Manfred Moser, Cole Bowden, Martin Traverso

It’s that time of the year where everyone gives excessively broad or niche predictions about the finance market, venture capital, or even the data industry. And we are now bombarded with “year-in-review” summaries where we find out just how much data is being collected to generate those summaries. End-of-year reflections are always useful because you can find patterns of what’s going well and what’s going poorly. It’s also good to pause and take stock of the things that did go well, because without that, you’ll only be looking at the list of things that you still have to do, and that isn’t healthy for anybody. In that spirit, let’s reflect on what we’ve been able to accomplish as a community this year, as well as what to look forward to in the next year!

Cleaning up the Trino pull request backlog

09 Jan 2023 | Cole Bowden

At some point in the lifecycle of a successful open source project, it reaches a point where the number of incoming pull requests (PRs) outpace the project’s ability to get code merged. It happens for a huge variety of reasons, including developers moving on to other projects before tying up every loose end, reviewers who miss a request for review, and because some stagnant PRs were never going to happen and should have been closed two years ago. The GitHub notification system doesn’t do anyone any favors, either. Having too many open PRs is a problem for a project, because they make it harder to tell what is being worked on and what may as well be dead code walking.

And when we cross 700 open pull requests in Trino, constantly adding a few more to the pile every week, what do we do? We clean it up! Let’s talk about how we’re doing it, why we’re doing it that way, and how we’re planning on preventing this from happening again. The end result should be some process improvements that make contributing to Trino a better, faster, and more painless experience.
