[jira] [Created] (MARMOTTA-421) UserService startup slow for big datasets

Sebastian Schaffert created MARMOTTA-421:
--------------------------------------------

             Summary: UserService startup slow for big datasets
                 Key: MARMOTTA-421
                 URL: https://issues.apache.org/jira/browse/MARMOTTA-421
             Project: Marmotta
          Issue Type: Bug
          Components: Platform
            Reporter: Sebastian Schaffert
            Assignee: Sebastian Schaffert


When starting up the system with a big dataset, the check if a user exists takes much too long because it looks for all occurrences of subject, predicate, object and context to see if a resource is used.

The solution is probably to not store user-related information in the triplestore at all and just use valueFactory.createUri() to create the user information.
