The DB on your side has indeed increased a lot. As for deleting manually any of the TSStorageData files, it could destroy your data base so we don’t recommend doing it.
If you want to reduce the size of your data base, you can manually delete old and unused Test Results through Test Studio. Still, keep in mind that Mongo DataBase will not free the unused space to the operation system, instead it will keep it for future use. Therefore, you have to execute db.repaitDataBase() towards TSStorageData in mongo shell. This will trigger a
compact command on every collection and free the unused space to the system. Before doing that however, please take a complete backup of your data base, because there is a chance the above operation to corrupt it.
Additionally, there is another option which is very rigid and can be used only if you don’t need any of your old test results. This said, if you decide to go with this, please take a complete backup of your database below proceeding with the bellow procedure.
When you are sure that you have collected the backup successfully and you don’t need any of the old test results you can do the following:
1. Stop your storage service.
2. Delete your database trough command line or with Robo 3T tool.
3. Start storage service.
4. Start Test Studio and run and schedule new run. Test Studio will recreate an empty data base.
I hope the above will help you. If you will require further assistance however, please do not hesitate to contact us again.
