During a storm, 311 and sensor feeds surge. Which responsibilities belong primarily to the ingestion layer of the Big Data architecture?
Select an answer to reveal the explanation.
Short Explanation
When sources flood the gates, ingestion is the shock absorber. Schemas, buffers, and replay keep analytics jobs from getting trampled at the door.
Full Explanation
The ingestion layer admits external data into the platform. Under surge, it typically owns contract management (schema registry), durable buffering, throttling, and replay so processing and serving remain stable. Dashboard rendering and business-rule redesign sit elsewhere. Clear layer ownership prevents operators from blaming warehouses for problems that buffering and schema control should handle upstream.
