We'll likely start an RFC discussion over at the foreman <a href="https://community.theforeman.org/" moz-do-not-send="true">Discourse</a> server soon: <a class="moz-txt-link-freetext" href="https://community.theforeman.org/">https://community.theforeman.org/</a>. Thanks All!

There are some big changes compared to pulp2, including: * Package profile, module profile,and repository list have to be uploaded on every applicability computation * Calls for applicability are not asynchronous (which makes sense as they are one profile at a time). Also keep in mind that due to the complexity of all the information needed, Katello has been the primary (and sometimes the only?) user of the service. For an example of what this might looks like, consider a repository that syncs some new packages. For 10,000 clients, it has to send the full package profiles for all 10,000 clients, as well as the other information in 10,000 api calls. In Addition our task workers will have to wait around for all 10,000 clients to be calculated. One last point is that katello already knows all the NVREA's for the rpms, which rpms are in which repositories, which artifacts are in which modules, and which packages are in what errata. Given all this, does it make sense for pulp to calculate the applicability? Or does it make sense for katello to? This assumes that no one else wants to use applicability in pulp3 (and given the barrier to entry is even higher than it was in pulp2, that may be possible). Justin </blockquote> </body> </html>
