RDI is an excellent choice when your application has a large number of users (>10,000 concurrent users), tables with many rows (tens to hundreds of millions), and a 80:20 read-write ratio.
These characteristics are commonly found in use cases in the financial services, e-commerce, and government verticals. Use cases include mobile banking, trade processing (caching reference data), real-time inventory (e-commerce), and tax payment portals. These use cases can have tens to hundreds of millions of rows of assets, such as bonds, accounts, products, and more.
