+# Git Object Deduplication demo
+
+## Script
+
+- Start with GDK with gitlab-ee master and gitaly master
+- Separate terminal: `gdk run db`
+- `rm -f .gitlab-bundle .gitlab-yarn && make gitlab-update gitaly-update`
+- `gdk run app`
+- create PUBLIC group parent
+- create PUBLIC project in parent group from pushing the local gitlab-ce copy
+- separate terminal: `bin/rails console
+- console:  `Feature.enable(:object_pools)`
+- create group for fork
+- fork into new group
+- console: `ActiveRecord::Base.logger.level = Logger::INFO`
+- console: `def sizes; Project.all.each { |p| printf("%4d %s\n", p.repository.raw.size, p.inspect) };nil; end`
+- console: `def pool(id); PoolRepository.find(id); end`
+- console: `def show_alt(p) ; system('cat', File.join('../repositories', p.repository.relative_path, 'objects/info/alternates')); end`
+- try to break stuff: `PoolRepository.all.each(&:destroy)`. Do projects still work?
