NAME

       cleanup_digikamdb  -  Cleanup  the  digiKam  databases  to reduce their sizes and increase
       access speed

SYNOPSIS

       cleanup_digikamdb [-t] [-T] [-p] [-h]

OPTIONS

       -t     Include thumbnail databases.

       -T     Only cleanup thumbnail databases.

       -p path
              Specify a different database path.  If this option is not set or the specified path
              is invalid, the entry from the configuration file will be used.

       -h     Show command line options.

DESCRIPTION

       cleanup_digikamdb will cleanup and optimize the digiKam database file.  This will, in most
       cases, lead to a smaller database  file  size  and  an  increased  access  speed,  because
       unneeded elements are removed from the database and data is optimized.

       The program will make sure that no instance of digiKam is running, because it is more safe
       to have no database access during the optimization process. It then will read the  digiKam
       configuration file and determine the database location.  In a final step the database will
       be optimized by invoking the sqlite command 'VACUUM;' on it.  If more then one database is
       found  in this location, cleanup_digikamdb will optimize every database found in this path
       and below.

       For further explanation, see the following description of  the  VACUUM  command  from  the
       sqlite3 website:

       When  an  object (table, index, or trigger) is dropped from the database, it leaves behind
       empty space.  This empty space will be reused the next time new information  is  added  to
       the  database.   But  in  the  meantime,  the  database file might be larger than strictly
       necessary.  Also, frequent inserts, updates, and deletes can cause the information in  the
       database  to  become  fragmented - scrattered out all across the database file rather than
       clustered together in one place.

       The VACUUM command cleans the main  database  by  copying  its  contents  to  a  temporary
       database  file  and  reloading  the original database file from the copy.  This eliminates
       free pages, aligns table data to be contiguous, and otherwise cleans up the database  file
       structure.
