Grzegorz Bizon requested to merge feature/gb/instrument-overwrite-project-service into master Jul 19, 2021

What does this MR do?

This merge request adds tracking of Projects::OverwriteProjectService that is used by import/export feature.

This services creates a possibly long-running transaction creating multiple subtransaction through Project.transaction(requires_new: true).

It is possible that this might affect performance in multiple places, especially performance of the new CI/CD builds queuing queries.
