Database Cleaning¶
The Database Cleaning tool analyzes your database files looking for entries to delete that have no matching files or folders. When this tool is run, the Core database is always cleaned. You can select additional databases for cleaning by selecting one of the extra options listed below:
Cleanup the Thumbnails database.
Cleanup the Faces database.
Cleanup the Similarity database.
Shrink all databases to ensure de-fragmentation, keeping the database as small as possible.
注釈
The last option leads to the vacuuming (shrinking) of the databases. Vacuuming is supported for both SQLite and MySQL. Database shrinking may take some time. In order to avoid database corruption during this operation, digiKam will display the following non modal dialog, and stop responding to user commands until the shrinking operation is complete.
