What could be a reason to choose embedding over referencing?

Choosing to embed data rather than using references can be beneficial when one document contains all necessary related data. This means that all the information relevant to a specific entity or use case is stored within a single document, allowing for more efficient data access and retrieval.

Embedding is particularly advantageous when the data is often accessed together. By minimizing the need for joins or additional queries, embedding enhances performance since all needed information can be retrieved in a single operation. This leads to reduced latency and improved read performance, which is valuable in many applications.

Therefore, when the data being used is closely related and will frequently be accessed together, embedding facilitates a simpler and more performant database design, making it easier to manage and query the data effectively.
