Welcome to your interview.
The question is on your right: Batch vs Streaming Data Processing. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
You're discussing pipeline design choices before building a new data movement workflow. You want to compare when a scheduled sync is enough and when continuous updates are a better fit.
Explain the difference between batch processing and streaming data.
