Will NextAuth + TypeORM + Sync = true run the syncronization on every session request?

[gtoshinakano]

Hello guys,

I know that it is not recommended to leave sync=true in production mode but, if I deploy NextAuth+MySQL TypeORM adapter on Vercel with synchronization = true, will it run every time some user calls the api/auth/[...nextauth].js file? Or will it cache in some way? Or will it be called once when the first user accesses a session?
