AWS Certified Data Engineer - Associate (DEA-C01) Exam Question Walkthrough
Gain clarity on a common AWS DEA-C01 exam question about processing streaming data from Kinesis to S3.
Your team needs to analyze streaming data from Amazon Kinesis Data Streams and store it in Amazon S3. Which AWS service can facilitate this process effectively?
A. Amazon Glue.
B. Amazon EMR.
C. AWS Lambda.
D. Amazon RDS.
Think before you scroll
Consider the specific requirements of handling streaming data and how each service interacts with Kinesis Data Streams. Focus on the capabilities of each service and their intended use cases.
The answer
The correct option is C. AWS Lambda. Lambda can process events from Kinesis Data Streams and store the results in Amazon S3. This solution is serverless and ideal for real-time data processing.
Why the other options lose
A. Amazon Glue. Glue is primarily used for ETL (Extract, Transform, Load) jobs. It’s not optimized for real-time streaming data processing like AWS Lambda.
B. Amazon EMR. EMR is designed for large-scale data processing and is heavier than necessary for simple data transfer tasks from Kinesis to S3. It adds complexity where Lambda offers a direct solution.
D. Amazon RDS. RDS is a relational database service and is not designed to handle streaming data processing. It lacks the capabilities necessary for real-time data flow from Kinesis.
The concept behind it
The underlying principle here is understanding the role of AWS services in data processing architectures. AWS Lambda is tailored for event-driven processing, making it suitable for scenarios where immediate action on streaming data is required. Recognizing the strengths and weaknesses of each service allows for better decision-making in exam scenarios.
Exam trap to remember
Remember: AWS Lambda is your go-to for processing streaming data in real-time. Avoid services that are better suited for batch processing or storage alone.
