django migration tables performance in database

i have two databases in Django project ,which is creating migration tables in both the databases.Now i want to know creating multiple migration tables in multiple databases is a problem or not? will this cause any performance issues on database or on entire datawarehouse?

Absolutely not a problem. The only time that the migration models are used are when you’re running commands related to them. (I can think of migrate, showmigrations, and sqlmigrate right off-hand. Possibly a couple others.)

Most importantly, they are not used during the routine operation of your system. They’ll have no effect on your project at all.

thanks for your help…
