What are GitLab parent-child pipelines?

They let a main pipeline spawn sub-pipelines for services, running independent but aggregated for status — perfect for monorepos.

How do GitLab DAG pipelines speed up CI/CD?

Needs: lets jobs skip stages, starting ASAP after deps finish — cuts wait times on unrelated work.

Does GitLab CI/CD replace multi-repo tools like Jenkins?

For complex setups, yes — native multi-project triggers and components handle it cleaner, with less config sprawl.
