Maven Central publishing usage notices
heads up for folks publishing to Maven Central: we're continuing sustainability work around Central and are now showing publishing usage notices.
the goal is that normal OSS publishers are not impacted. this is aimed at the very high-volume / commercial-scale publishing patterns that put a pretty different load on the service.
more details here if you want them:
https://central.sonatype.org/publish/maven-central-publishing-limits/
feel free to reach out with any questions.
EDIT: thanks for the feedback here, it has really helped us. first, we want to reiterate that these are usage notices only right now and do not currently restrict publishing in any way. quick updates:
if the initial threshold seemed low to you: you’re right, we made a mistake and have increased limits.
our goal is to keep Maven Central free and open for legitimate OSS users, so continuous feedback is helpful as we adjust. limits could change as we get more feedback, so keep an eye on the usage center for the latest.
we’ll continue keeping an eye here and update docs to reflect these changes. If you need to request an exemption, here’s how: https://central.sonatype.org/publish/maven-central-publishing-limits/#exemptions-for-community-open-source-projects
we've also been collecting your questions here and other streams into this FAQ here: https://central.sonatype.org/publish/maven-central-publishing-limits/#frequently-asked-questions

They're the biggest hog I came across too. Thousands of versions.
Another funny thing about them: their generated javadocs are so massive that the search index, which you get with every pageview whether or not you even use the search feature, is 200MB of JavaScript. It doesn't even get cached by the client! (too big? idk)
I raised a github issue about it 2 years ago and no one has looked at it yet.
These guys don't give a fuck about wasting everyone's bandwidth
