Remove file_template_project_id column from namespaces table and move it to 'namespace_settings'
Namespaces table is very wide, and used in many places, it's basically backbone of GitLab. Because it used so many times and holds much information, sometimes it contributes to the slow performance.
Removing file_template_project_id
and moving it to 'namespace_settings' would make the table slimmer and probably more performant thanks to that.
