The Polymorphic Pattern: NoSQL Data Modeling with Redis

With SQL databases, you need separate tables to store specifics about the different types of products you are working with. To get all your products, all tables with all their separate specifics must be joined together, which creates serious overhead.

With Redis Stack, all schemas are flexible and let you distinguish type fields that group collections together. Start reducing the number of collections used to store data and simplify app logic in queries using the polymorphic pattern with Redis Stack.

So what is happening with the fields that are null i am not understing that, is it ok to let fields in null?

I don't see any polymorphic pattern here, it a model who contains all the data and redis don't show null fields, we can do the same with sql. Maybe there is something i didn't understand, can you explain more please
