Have you ever had to build a query plan?

The query plan is a sequence of actions that the database performs to retrieve the required data. In the frontend, it is usually not necessary to directly construct a query plan, but you can optimize server requests, for example, by combining filters, sorts, and pagination to minimize load.

If we're talking about GraphQL, then you can manually formulate queries, selecting only the necessary fields, which is similar to building a query plan in terms of data optimization.

An example of a simple GraphQL query with field selection:

{
  user(id: "1") {
    id
    name
    email
  }
}
