by now Gerrit trigger depends on Project, Branch and files. It would be great to select jobs through TOPIC name. We dont use Branches (CI), and we only 1 project. So the only trigger can be the files. Which is not enough sometimes, an example. If the change only contains code smells fixes such as naming convention magic strings, etc - then build job is enough to be executed on that file. But if I made an API change then the TOPIC name would something else on the same file change.
