GitLab merge requests are used in open-source projects or in some corporate workflows to manage changes from contributors and to initiate code review before such changes are merged.
When you create a merge request, you tell others about the changes you want to push to the original repository. The maintainers of that repository can then review your changes, discuss them, and integrate them into the base branch.
As a merge request author, you can manage your merge request lifecycle directly within DataGrip:
Create a merge request.
View details of your merge request in the Merge Requests tool window.
Merge or close your merge request.
Create a merge request
In the main menu, go to .
In the Merge Requests tool window that opens, click
Create Merge Request in the top-right corner.A new tab opens with a merge request draft.
Click the name of the base repository on the left and specify the branch that will receive the updates.
Click the name of the head repository on the right and specify the branch with the changes that will be added to the base repository.
If you have a project that uses multiple remote repositories, you can change the head repository in this popup as well.
Specify the name for your merge request in the Title field, and, optionally, provide a description of the changes to be applied through your request and add reviewers.

Select a particular commit to filter the list of changes.
Create a local branch based on incoming changes: open a merge request, click the branch with incoming changes, and choose Checkout 'branch name' in the context menu.
Investigate branch-related changes in the Log tab of the Git tool window: open a merge request, click the branch with incoming changes, and choose Show 'branch name' in Git Log in the context menu.
This will help you navigate the code related to this merge request, make sure the project builds and the tests pass.

Work with received feedback
If someone left comments to your merge request, you can resolve them or leave your answers directly in DataGrip.
In the main menu, go to or click
in the tool window bar on the left.Select the merge request from the list and double-click it. DataGrip opens an overview of the selected merge request.
Click the branch with incoming changes and choose Checkout 'branch name' in the context menu.
