Hi all, while the new build machines are fast, some of you pointed out we're now spending a relative high amount of time downloading maven dependencies, this problem being compounded by the fact we "nuke" idle slaves shortly after they become idle.
I just spent the day testing a distributed file system, and it's now running in "production". It's used exclusively to store the Gradle and Maven caches. This is stateful and independent from the lifecycle of individual slave nodes. Unfortunately this solution is not viable for Docker images, so while I experimented with the idea I backed off from moving the docker storage graph to a similar device. Please don't waste time trying that w/o carefully reading the Docker documentation or talking with me :) Also, beyond correctness of storage semantics, it's likely far less efficient for Docker. To learn more about our new cache: - https://github.com/hibernate/ci.hibernate.org/commit/dc6e0a4bd09fb3ae6347081243b4fb796a219f90 - https://docs.aws.amazon.com/efs/latest/ug/how-it-works.html I'd add that - because of other IO tuning in place - writes might appear out of order to other nodes, and conflicts are not handled. Shouldn't be a problem since snapshots now have timestamps, but this might be something to keep in mind. N.B. Please never rely on this as "storage": it's just meant as cache and we reserve the right to wipe it all out at any time.
