You do not need uuid unless you want to import records that you
already have and want to replace them.
If you use
id_map={}
db.table1.import_from_csv_file(ifile1, id_map=id_map)
db.table2.import_from_csv_file(ifile2, id_map=id_map)
the id_map={} makes sure all references between table1 and table2 are
preserved. References to records that are not imported may still be
broken.
