Firebase Firestore Data Modeling Tips (NoSQL)

Correctly structuring data models when setting up Firestore directly determines the future speed and costs of the application.

In NoSQL, data duplication is not an error, but a necessity. Embedding the username in every comment saves you from join operations.

// Storing author data in each comment document reduces read counts
{
   id: "comment_1",
   text: "Great project!",
   author: {
      uid: "123",
      name: "Fahri",
      avatar: "url..."
   }
}
