This plugin provides a console command that allows you to delete all tables and reimport them from the dump.
Refer to this Matomo FAQ.
Put the dump files in the sql folder.
You can specify more than one dump file.
An absolute or relative path can be specified.
Execute the command like:
./console reset-database --dump="/path/to/dump.filename.first.sql" --dump="../path/to/dump.filename.second.sql"
