This script postprocesses XML dumps from dumpBackup.php to add
--stub=<type>:<file> To load a compressed stub dump instead of stdin
--prefetch=<type>:<file> Use a prior dump file as a text source, to save
pressure on the database.
- (Requires the XMLReader extension)
--quiet Don't dump status reports to stderr.
--report=n Report position and speed after every n pages processed.
(Default: 100)
--server=h Force reading from MySQL server h
+ --output=<type>:<file> Write to a file instead of stdout
+ <type>s: file, gzip, bzip2, 7zip
--current Base ETA on number of pages in database instead of all revisions
--spawn Spawn a subprocess for loading text records
