Lambda Architecture

The Lambda Architecture is a traditional big data processing pattern designed to handle both real-time and batch processing needs using two separate layers. It consists of a batch layer for comprehensive, accurate processing of large historical datasets, and a speed (or streaming) layer for low-latency processing of recent data, with results merged in a serving layer. Modern streaming systems like RisingWave, especially within a Lakehouse context, often aim to simplify or replace the Lambda Architecture with a more unified approach like Kappa.
