So far we have managed to automatically determine the schema and sharding key for ~80% of tables. The remaining ~20% will require manual input. For the remaining tables, create `Draft` merge requests that partially update the database dictionary entries, and prompt the assignee/reviewer to choose one of the following for each entry: - Add a sharding key - Add a desired sharding key - Set the schema to `gitlab_main_clusterwide` - Create a follow-up issue (or link an existing one) for the entry if none of the above options are currently possible
