Final answer:
It is false that demo data should be loaded on any instance in the release chain; while it could be useful for development or testing, it should never be used in the production environment.
Step-by-step explanation:
The statement is false; it is not best practice to load demo data on any instance used in your release chain. The release chain usually includes different environments, such as development (dev), staging, and production (prod). Demo data is often used in development or staging environments for testing but should be strictly avoided in a production environment. The production environment is meant to replicate real-world operations with actual data, and using demo data can lead to inaccurate testing results, data pollution, and potential issues with data privacy and integrity.
In development environments, using demo data can be useful for developers to build and test features without compromising the integrity of real data. However, even in development or staging environments, it's usually advised to use sanitized copies of production data or realistic test data that mimics production data closely to ensure accurate testing and development.
