Shows a runnable Scala Akka application that wires Kafka producers, Spark Streaming micro-batches, the Spark–Cassandra connector and Cassandra tables to implement a Lambda-style pipeline with exactly-once guarantees and incremental model updates via Spark ML (online SGD). Demonstrates collocating Spark and Cassandra nodes to leverage co-located Spark+Cassandra for data locality, time-series schemas that use clustering keys and time UUIDs to avoid overwrites, and using Kafka topics for backpressure and durable replay. Includes code, a weather time-series demo, and operational fault-tolerance notes.
