 Listing of `tables` is not mandatory, if they are not listed, then all of the tables from the source database will be copied to the target database. With the truncate option, given tables can be cleared in the target database before loading, while SQL ccommands can be run with `runAfter` and `runBefore`
 
 **Important to note that the tables must exist** in the target database, the transfer does not create them.
