SAP-C02 Q323 · Streaming

Question

A company processes environmental data. The company has set up sensors to provide a continuous stream of data from different areas in a city. The data is available in JSON format. The company wants to use an AWS solution to send the data to a database that does not require fixed schemas for storage. The data must be sent in real time. Which solution will meet these requirements?

Accepted Answer

**Answer B: Amazon Kinesis Data Streams → Amazon DynamoDB** satisfies every requirement:

1. **Continuous stream of data**: Kinesis Data Streams is purpose-built for real-time streaming ingestion. It captures data continuously with sub-second latency, making it ideal for IoT sensor data.

2. **Real-time processing**: Kinesis Data Streams provides true real-time data delivery. Consumers (e.g., AWS Lambda, KCL applications) can read and process records within milliseconds of arrival, then immediately write to DynamoDB.

3. **No fixed schema**: DynamoDB is a **NoSQL key-value and document database**. It does not require a predefined schema beyond the primary key. Each item can have different attributes — perfect for JSON sensor data that may vary across different sensor types or areas.
