Lambda architecture is a design pattern used in big data processing that effectively combines batch and streaming data processing methods. This approach allows organizations to process massive amounts of data in real-time while also enabling the analysis of historical data through batch processing.

The batch layer handles large volumes of data collected over time, performing complex computations and generating pre-computed views or results. This layer is essential for processing extensive datasets, allowing for detailed analytics and insights. In contrast, the streaming layer processes data in real time, dealing with incoming data streams as they arrive, which provides up-to-the-second insights and allows for immediate data-driven decision-making.

The combination of these two layers ensures that the system can provide both reliable, comprehensive analytics through batch processing and instantaneous updates and insights through streaming, making it highly effective for applications that require both historical analysis and real-time data interaction.

Other options do not capture the essence of Lambda architecture. For instance, recursive processing is not a fundamental component of the architecture, and online/offline processing typically refers to broader concepts rather than the specific integration of batch and streaming processes.
