Question: Cloud Dataflow is a fully managed service for transforming and enriching data in stream (real time) and batch (historical) modes with equal reliability and expressiveness. Knowing this, where does Cloud Dataflow fit in the big data processing model?
- Storage
- Analyze
- Ingest
- Process
Explanation
Cloud Dataflow fits the process phase because it transforms and enriches data after ingestion and before storage or analysis. It supports both stream processing and batch processing using a unified pipeline model. Dataflow pipelines can apply operations such as filtering, grouping, joining, and aggregation. This makes Cloud Dataflow the Google Cloud service used to process data within big data workflows.
Why the other options are incorrect
Storage describes where data is retained, not where Cloud Dataflow transforms data.
Analyze describes insight generation with services such as BigQuery, not pipeline processing.
Ingest describes bringing data into the system, which aligns more closely with Pub/Sub.
