The Lambda Architecture combines low latency real-time frameworks with a comprehensive, high throughput MapReduce batch framework through distributed frameworks like Hadoop and Spark. Observe, while data is processed real-time as Spark DStreams, simultaneous batch processing takes place through the stored data from HDFS. A NoSQL store (Cassandra) stores the consolidated view from stream and batch
