Using Shared Data Sources

Some use cases require a large amount of read-only data, which is impractical to load into every environment.

For these situations, we recommend using an externally hosted data store, and allowing shared remote access from your Preview environments.

The approach of using external data stores could also be used for mutable data types (ie, those which are both written and read from copies of your application), however we do not recommend this due to potential conflicts which can arise.
