HyukjinKwon opened a new pull request, #48775: URL: https://github.com/apache/arrow/pull/48775
### Rationale for this change Currently, workflows use `cancel-in-progress: true` unconditionally, which cancels builds even on the main branch when multiple commits are pushed in quick succession. This prevents proper validation of main branch commits and can cause incomplete CI runs for scheduled builds. Here is one example: <img width="892" height="453" alt="Screenshot 2026-01-08 at 10 04 53 AM" src="https://github.com/user-attachments/assets/cd475787-d1b0-43a0-8fa2-30e59726f489"; /> ### What changes are included in this PR? Changed `cancel-in-progress` from `true` to `${{ github.event_name == 'pull_request' }}` in workflows. Now only pull request builds are cancelled when new commits are pushed. Main branch pushes, scheduled runs, and manual runs will always complete. ### Are these changes tested? Will be tested in CI. ### Are there any user-facing changes? No, dev-only. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
