The described batching algorithm does seem like it has a high potential to not work well for Rust, with our long turnaround times, and high intermittent rates. I’d be more comfortable adopting it if it supported our existing workflow and let us gradually experiment with others.
If bors-ng is going to be maintained, and it can support our workflow, and somebody is willing to do the work of the transition, and preferably if it can remain under the venerable ‘bors’ account, then it might be worth pursuing. We’ve long wanted to replace homu. I’m glad somebody has finally done the work - I didn’t realize it was ongoing.
Here’s what it looks like in action: https://bors-app.herokuapp.com/
Sadly there’s no activity in the queue.
