Get faster and more flexible pipelines with a Directed Acyclic Graph

GitLab has introduced a new feature called Directed Acyclic Graph (DAG) that enhances CI/CD pipeline efficiency by allowing jobs to run out of order based on dependencies rather than rigid stage sequences. This feature is available for free on both GitLab.com and self-managed versions, and it significantly reduces pipeline execution time by enabling jobs to commence as soon as their direct dependencies are completed, irrespective of other ongoing jobs in the same stage. The DAG feature is particularly beneficial in scenarios such as monorepo patterns, where different components like iOS, Android, and web apps can be independently built, tested, and deployed, and in pipelines with lengthy tests that benefit from early initiation. DAG's implementation involves using a new keyword, needs, in the .gitlab-ci.yml configuration file to specify job dependencies, allowing for a more flexible and time-efficient pipeline execution.
