Although Real-Time Analytics may seem like a recent trend, there have been attempts at it stretching back several decades. This talk first explores the "classic streaming stack," based on the Lambda architecture, its origin, and why it didn't pick up amongst data-driven organizations. The Real-Time Analytics (RTA) Stack is a lean, cloud-native, and economical alternative to classic streaming architectures, which aims to make event-driven real-time applications viable for organizations. The second half of the talk explores the RTA Stack in detail, including its core components, its purposes, and how the Kappa architecture influenced them. We will also outline a few considerations before planning a new streaming application within an organization. The talk concludes by discussing the challenges in the streaming world and how vendors are trying to overcome them in the future.
