##### Upload

  - As a user, I can copy an Erratum and all the RPM packages it references and all the RPM dependencies from one repository to another repository - K2

  - Some content types create a new content unit in the destination repo instead of just copying, e.g. yum_repo_metadata_file

  - Special copy for modules \[TBD\]

#### Not much yet discussed use cases

##### Content Protection

  - As an authenticated user, I can use key based authentication to allow/disallow access to content served by the content app - K3

  - As an authenticated user, I can use user/password based authentication to allow/disallow access to content served by the content app.

##### Applicability

  - As an authenticated user, I can trigger an applicability for a consumer.

  - As an authenticated user, I can trigger an applicability for a repository.

##### Rsync Distributor

  - As a user i can distribute rpm content using a remote server.

## Pulp 2 features not present in Pulp 3

  - "gpgkey" importer setting - only used by pulp-agent.

  - "generate_sqlite" - sqlite files are only used by yum as an optimization. DNF does not use them and has no plans to. Performance gains marginal.

<!-- end list -->

  - they are also used by the "repoview" feature which we will also leave out of 3.0. Making browseable publications will hopefully be solved in the core.

<!-- end list -->

  - As a user, I can have publish skip one or more content types, e.g. drpm, errata, etc

<!-- end list -->

  - We can't think of a use case for this. Maybe export of only RPMs and Errata, see export use case.
