Streetlight sensors speak constrained field protocols, while the analytics platform expects Kafka producers. Which pattern best bridges that gap?
Select an answer to reveal the explanation.
Short Explanation
Tiny pole sensors are not laptop Kafka clients. A field gateway gathers frames, batches them, and speaks Kafka upstream—like a neighborhood post office for IoT. That is the usual bridge into the city bus.
Full Explanation
IoT devices often lack the resources or protocols to act as first-class Kafka producers. Gateways aggregate, buffer, and translate sensor frames into producer publishes on municipal topics. Direct heavy clients on every device, email drops, or local MapReduce on poles miss the ingestion pattern Syllabus Chapter 8 emphasizes. Gateway-to-Kafka is the standard conceptual path from field networks into the Big Data messaging layer.
