Which Firestore Data Structure (References or Duplication) Optimizes Data Retrieval for Products and Providers?

Optimal Data Structuring in Firestore for Efficient Data Retrieval

In the realm of Firestore data modeling, there is no absolute "correct" approach. The most suitable structure depends on your application's specific needs and query requirements.

As you have conceptualized, you intend to create two collections: a "Providers" collection containing provider details and a "Products" collection encompassing product information, including provider references. This approach is a valid strategy.

There are two primary methods for referencing providers in products: utilizing provider IDs or duplicating provider objects within product documents. While both methods are viable, the optimal choice hinges on your requirements and potential trade-offs.

Keeping References: Pros and Cons

Pros:

• Simpler code for data writing
• Significantly reduced data storage
• Minimal updates required for provider information changes

Cons:

• Additional database calls for retrieving provider data
• Potential performance overhead with large numbers of products and distant providers

Duplicating Data: Pros and Cons

Pros:

• Faster read performance with all product and provider information in a single document
• Simplified queries

Cons:

• More complex writing code
• Increased data storage and memory usage
• Need to maintain data consistency in case of provider changes

Considerations for Choice

Your decision should be influenced by factors such as:

• Frequency of provider changes
• Number of products associated with each provider
• Performance needs of your application
• Cost considerations (Firestore reads are more expensive than Realtime Database reads)

If provider data is frequently updated, keeping references is preferable to minimize write complexity and data consistency issues. However, if performance is more critical and read queries are expected to be frequent, duplicating data may enhance performance.

Remember that data duplication is a common technique in NoSQL databases to optimize read operations at the expense of write complexity and data redundancy. By considering your specific requirements, you can determine the most appropriate data structuring approach for your application.
