What are the impacts of including cache in your architecture? | Architectural Simplification

Description

In this episode of Architectural Simplification, Cockroach Labs Technical Evangelist Rob Reid answers the questions of what the impacts are of including cache in your architecture from the perspective of read performance. Rob's test involves a service that writes to a relational database and to a cache where he simulates writes and reads versus a services that writes to a relational database that can scale for both reads and writes.
