> A demostration for change set - > https://github.com/apache/pulsar/pull/20974 While I think it is great to start with Spotless for little projects or when you start from scratch, appling a patch that changes 3.000+ files will make it very hard to rebase all the pending PRs and also to cherry pick changes to older branches that we support. I think that this is not a good option for Pulsar at this stage. Maybe if we had a configuration that doesn't change so many files....
