Question

A company processes environment data. The has a 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 send in real time. Which solution will meet these requirements?

Accepted Answer

Let's map each requirement to the solution:

**1. Continuous stream of sensor data (real-time):**
- Amazon Kinesis Data Streams is purpose-built for **real-time** data ingestion and processing with sub-second latency.
- Consumers (e.g., AWS Lambda or KCL applications) read from the stream and write to DynamoDB in near real-time.
- Kinesis Data Streams gives you the lowest latency among the streaming options because you control the consumer and processing logic directly.

**2. JSON format data:**
- DynamoDB natively stores data as JSON-like attribute-value pairs. JSON documents map naturally to DynamoDB items without transformation.

**3. No fixed schema required:**
- **Amazon DynamoDB is a NoSQL key-value/document database that does NOT require a fixed schema.** Each item can have differen
