[digikam] [Bug 318363] New: Bad performance of file renames (thumbnail recreation?)

            Bug ID: 318363
           Summary: Bad performance of file renames (thumbnail
                    recreation?)
    Classification: Unclassified
           Product: digikam
           Version: 3.1.0
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Advanced Rename
          Assignee: [hidden email]
          Reporter: [hidden email]

Dear devs

I was just renaming a few dozen files in an album using the rename function.
All I did was changing the extension to lower case, i.e. [name].[ext]{lower}.
The process ran very slowly with a lot of HDD load. Apparently, the thumbnail
is recreated for every image plus possibly some other database stuff (I saw the
thumbnail DB grow while renaming was in progress).
From my point of view, should a simple changing of the filename reference in
the database not be enough instead of creating a whole new image entry?

Thanks for your consideration.

Reproducible: Always

Steps to Reproduce:
Rename a bunch of files.
Actual Results:  
It takes quite some time and causes a lot of disk load.

Expected Results:  
It should be quite fast, because basically only one string should be changed in
the database.

This seems to be related to #305359. I'm using SQLite by the way.
