MongoDB::repair
(PECL mongo >=0.9.0)
MongoDB::repair — Repairs and compacts this database
说明
public
MongoDB::repair ([
bool
$preserve_cloned_files = FALSE [,
bool $backup_original_files = FALSE ]] ) :
array
This creates a fresh copy of all database data. It will remove any corrupt data and compact and large stretches of free space it finds. This is a very slow operation on a large database.
This is usually run from the shell or the command line, not the driver.
It is equivalent to the function:
<?php
public function repair() {
return $this->command(array('repairDatabase' => 1));
}
?>
参数
-
preserve_cloned_files -
If cloned files should be kept if the repair fails.
-
backup_original_files -
If original files should be backed up.
返回值
Returns db response.
