@caicancai thanks for the PR. We should also add this to Iggy's website [iggy.apache.org]
Do you want to contribute there as well? https://github.com/apache/iggy-website

@hubcio @kparisa Thank you for your reply. If this PR is merged, I will update this document to the official website.

Hey,
Thanks for the contribution, we need to verify why does the CI check fails, as it looks like some issue with resolving the origin.

Wild guess: most probably because the contributor forked just the master branch (this is the default Github behavior).

Do you mind if I try to fix it?

Feel free to do it :)

@spetz @martin-g Your guess is correct, because the other PR #1712 did not fork the master branch, and its CI did not fail.

Your guess is correct

Thanks for confirming!
I have faced this issue in the past too!

https://github.com/apache/iggy/blob/master/.github/scripts/detect-changed-files.sh could be dropped in favor of action like https://github.com/Ana06/get-changed-files

I think it should work now thanks to #1738
