Actions Control the concurrency of workflows and jobs - GitHub Docs
Teaches how to use the concurrency key in GitHub Actions workflows to limit the number of concurrent workflow runs or jobs and cancel in-progress runs when new ones are triggered.
When To Use
Use when you need to prevent multiple workflow runs from executing simultaneously or when you want to automatically cancel outdated builds in favor of newer ones.

What This Skill Covers
-
- GitHub Actions / - How-tos / - Write workflows / - Choose when workflows run / - Control workflow concurrency
- Main sections:
In this article,Using concurrency in different scenarios,Example: Using concurrency and the default behavior,Example: Concurrency groups,Example: Queueing multiple pending runs.
Workflow
- Open the most relevant file under
docs/for the exact documented workflow and wording. - Open
schemas/files for exact structured contracts. - Open
examples/files for concrete requests, commands, snippets, and manifests. - Do not add behavior or configuration that is not present in the attached source files.
