### Issue Indeed, the `cancel-in-progress` is rather misleading. Need to read the [documentation](https://docs.github.com/en/actions/learn-github-actions/workflow-syntax-for-github-actions#concurrency) thoroughly: > Concurrency ensures that only a single job or workflow using the same concurrency group will run at a time. > When a concurrent job or workflow is queued, if another job or workflow using the same concurrency group in the repository is in progress, the queued job or workflow will be pending. Any previously pending job or workflow in the concurrency group will be canceled. To also cancel any currently running job or workflow in the same concurrency group, specify cancel-in-progress: true. Thus once we define `concurrency` then at least the pending jobs are going to be canceled. ### Solution In order to "disable" concurrency groups for push events we need to generate unique group identifiers for pushes while keeping the pull requests' identifiers for pull request events. The following can work: On push: `apache/arrow-<commit-hash>-<workflow-name>` On pull request: `apache/arrow-<pull-request-reference>-<workflow-name>` ### Implementation We need to change the currently used `${{ github.ref }}` to another expression which conditionally changes based on the event kind. We can use the following expression instead: ``` ${{ github.head_ref || github.sha }} ``` See `github.head_ref`'s [documentation](https://docs.github.com/en/actions/learn-github-actions/contexts#github-context): > The base_ref or target branch of the pull request in a workflow run. This property is only available when the event that triggers a workflow run is either pull_request or pull_request_target. -- This is an automated message from the Apache Git Service.
