DBS-C01 Workload-Specific Database Design Practice Question
A company needs to choose a database for a real-time analytics workload that requires sub-second query latency on streaming data. Which TWO AWS services are most suitable?
⚠ Common exam trap
Many exam-takers confuse low-latency caching services like DAX or traditional databases with materialized views as suitable for real-time streaming analytics, overlooking that only purpose-built time-series databases or services with native streaming ingestion can guarantee sub-second query latency on continuous data streams.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon Redshift with streaming ingestion from Kinesis.
Amazon Timestream is purpose-built for time-series data and provides sub-second query latency on streaming data via its dedicated query engine and automatic tiering between in-memory and magnetic stores. Amazon Redshift with streaming ingestion from Kinesis enables real-time analytics by directly consuming Kinesis data streams into Redshift materialized views, allowing sub-second queries on fresh data without batch loading.
