J'utilise mysqldump database > output.sql pour vider toutes les données d'une base de données. La taille du fichier de sortie est d'environ 3,3 Go. Je l'importe en utilisant mysql < output.sql Cependant, il fonctionne depuis plus de 24 heures et n'est toujours pas terminé.
Est-ce normal ? Existe-t-il un moyen d'accélérer l'importation ?
