I asked for an update on the Apache org GitHub Actions usage stats from Gavin McDonald on the-asf slack in this thread: https://the-asf.slack.com/archives/CBX4TSBQ8/p1662464113873539?thread_ts=1661512133.913279&cid=CBX4TSBQ8 .
I hope we get this issue resolved since it delays PR processing a lot. -Lari On 2022/09/06 11:16:07 Lari Hotari wrote: > Pulsar CI continues to be congested, and the build queue [1] is very long at > the moment.
