Hi guys and gals. forgive me if this questions is in the wrong place, new to the forum and sql development in general.
what I am wondering is how the design of a database schema (logical design of tables and queries) is affected by horizontal scaling given the constraint that the data being stored is unique. what i mean by this is that each server is not a mirror of a master server. an example would be a database like facebook.
thanks for taking the time to read, looking forward to your replies!!
