How is horizontal scaling used in database design?
Horizontal scaling involves adding more machines to cope with growing workloads. This article will only highlight database design decisions required for a scalable application. At the database level configuration, schema design, indexing, and query design affect the capability of a database to scale.
When do you need a scalable data warehouse?
However, when working with larger or more complex datasets, as well as an increasing amount of concurrent users, the performance depends largely on the underlying analytical database – whether this is built into the application as part of a single-stack tool, or implemented via a separate data warehouse layer.
