prisma nested fields

is it okay in terms of performance to have many nested fields in prisma?

 
const user = await prismadb.user.findUnique({
      where: { id },
      include: {
        licenses: {
          include: {
            subscription: {
              include: { organization: { include: { admin: true } } },
            },
          },
        },
      },
    });

 
const user = await prismadb.user.findUnique({
      where: { id },
      include: {
        licenses: {
          include: {
            subscription: {
              include: { organization: { include: { admin: true } } },
            },
          },
        },
      },
    });

Hi @Emi 👋 Having to include many nested fields in your queries can have performance implications. Each level of include results in an additional SQL query. For example, if you have a user model that includes licenses, which in turn includes subscription, which includes organization, which includes admin, this would result in multiple SQL queries. The more nested your include statements are, the more SQL queries will be generated, which could potentially impact performance. There are open issues with respect to this here and here. Also you should note that we recently released the relationJoins preview feature which aims to improve the performance of nested reads as stated here
