Categorize existing Object Storage buckets
As part of the Object Storage Working Group we want to document the current state of the Object Storage in GitLab.
- [x] Identify Bucket Ownership - [internal google doc](https://docs.google.com/spreadsheets/u/0/d/1Gsq0EVMcjCIUAiDDqNXfoNxsCjBpX1_XBOaV07eiQgA/edit)
- [x] Categorize how features interact with the Object Storage
# Categorization
We thought it was possible to categorize our Object Storage interaction following the three upload technologies defined in our [documentation].
After digging into this it was clear that those categories do not cover the entire spectrum of features we have.
| Feature | upload technology | uploader | bucket structure |
|------------------------------------------|-------------------|-----------------------|-----------------------------------------------------------------------------------------------------------|
| job artifacts | direct_upload | workhorse | `/artifacts/<proj_id_hash>/<date>/<job_id>/<artifact_id>` |
| pipeline artifacts | carrierwave | sidekiq | `/artifacts/<proj_id_hash>/pipelines/<pipeline_id>/artifacts/<artifact_id>` |
| live job traces | fog | sidekiq | `/artifacts/tmp/builds/<job_id>/chunks/<chunk_index>.log` |
| job traces archive | carrierwave | sidekiq | `/artifacts/<proj_id_hash>/<date>/<job_id>/<artifact_id>/job.log` |
| autoscale runner caching | N/A | gitlab-runner | `/gitlab-com-[platform-]runners-cache/???` |
| backups | N/A | s3cmd, awscli, or gcs | `/gitlab-backups/???` |
| git LFS | direct_upload | workhorse | `/lsf-objects/<lfs_obj_oid[0:2]>/<lfs_obj_oid[2:2]>` |
| design management files | disk buffering | rails controller | `/lsf-objects/<lfs_obj_oid[0:2]>/<lfs_obj_oid[2:2]>` |
| design management thumbnails | carrierwave | sidekiq | `/uploads/design_management/action/image_v432x230/<model_id>` |
| generic file uploads | direct_upload | workhorse | `/uploads/@hashed/[0:2]/[2:4]/<hash1>/<hash2>/file` |
| generic file uploads - personal snippets | direct_upload | workhorse | `/uploads/personal_snippet/<snippet_id>/<filename>` |
| global appearance settings | disk buffering | rails controller | `/uploads/appearance/...` |
| topics | disk buffering | rails controller | `/uploads/projects/topic/...` |
| Avatar images | direct_upload | workhorse | `/uploads/[user,group,project]/avatar/<model_id>` |
| Import/export | direct_upload | workhorse | `/uploads/import_export_upload/???` |
| GitLab Migration | carrierwave | sidekiq | `/uploads/bulk_imports/???` |
| MR diffs | carrierwave (?) | sidekiq (?) | `/external-diffs/merge_request_diffs/mr-<mr_id>/diff-<diff_id>` |
| package manager archives | direct_upload | sidekiq | `/packages/<proj_id_hash>/packages/<pkg_segment>/files/<pkg_file_id>` |
| package manager archives | direct_upload | sidekiq | `/packages/<container_id_hash>/debian_*_component_file/<component_file_id>` |
| package manager archives | direct_upload | sidekiq | `/packages/<container_id_hash>/debian_*_distribution/<distribution_file_id>` |
| container image cache (?) | direct_upload | workhorse | `/dependency-proxy/<group_id_hash>/dependency_proxy/<group_id>/files/<proxy_id>/<blob_id or manifest_id>` |
| terraform state files | carrierwave | rails controller | `/terraform/<proj_id_hash>/<terraform_state_id>` |
| Pages content archives | carrierwave | sidekiq | `/gitlab-gprd-pages/<proj_id_hash>/pages_deployments/<deployment_id>/` |

# CarrierWave interactions
The following table contains the list of files interacting with carrierwave, it is a good indicator of the number of features as well as a checkpoint for the categorization table above.
