Big Data Architectures: Lambda and Kappa Explained Big data teams design pipelines to handle large volumes and fast streams. Two common patterns are Lambda and Kappa. This article explains what each pattern does, when to choose one, and what trade-offs you should expect. Lambda architecture Lambda uses three layers to balance accuracy and timeliness. The batch layer stores raw events and recomputes comprehensive views on a schedule. The speed (streaming) layer processes new events quickly to give low-latency results. The serving layer makes the latest batch and stream views available for queries. ...
