DEA-C01 Data Ingestion and Transformation Practice Question
A data engineer needs to ingest streaming data from a social media API into Amazon S3 for batch analytics. The data arrives at a rate of 500 records per second. Which service should be used to capture the stream?
⚠ Common exam trap
Test-takers frequently confuse SQS's message queueing with Kinesis's stream processing, overlooking that SQS lacks ordered, replayable, and high-throughput streaming capabilities required for real-time data ingestion into S3.
