Overfetching

Optimize provides recommendations to help you identify and resolve performance issues caused by over-fetched data.

The following query might be overfetching data in queries on the User model:

await prisma.user.findMany({
  where: {
    email: { contains: "gmail" },
  },
  include: {
    links: true,
  },
});

What is the problem?

Retrieving data from all columns of a table, especially in large tables or those with complex relationships, can result in:

• Increased load times: Fetching more data than necessary prolongs query processing and data transfer times.
• Greater resource consumption: Retrieving unnecessary fields places strain on memory and CPU resources, both in the database and on the machines running your application.
• Higher costs: Reading and transferring excess data can lead to increased processing costs.
• Security risks: You might unintentionally expose sensitive data that should remain within the database.
