GitHub Actions parallel steps
Steps can run concurrently within one job, with separate logs and execution:
background: true: starts a step asynchronously; execution proceeds immediately.wait: blocks until specific named background steps finish.wait-all: blocks until all earlier background steps finish.cancel: gracefully stops a background step, including a long-running service.parallel: groups concurrent steps and waits for the group to finish; shorthand for background steps followed by a wait.
Reference: workflow syntax.
