AddItemToSet vs StoreRelatedEntities

Question

I am trying to understand when someone would use AddItemToSet vs StoreRelatedEntities.

It seems the former is a way to associate a set label with a string-based item handle.

The latter is a way to associate two entities, which seems like a more generalized operation.

What is it that AddItemToSet does that StoreRelatedEntities can't do?

Thanks

Answer 1

The AddItemToSet API in ServiceStack.Redis is a 1:1 mapping that calls Redis' Server SADD Operation, i.e. adds an item to a Redis SET.

The StoreRelatedEntities is a higher-level operation that also maintains an index containing relationship between the entities described in detail in this Storing Related Entities in Redis answer.
