Your question is System Design for Data Ingestion with Trade-offs. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Design a system for a given use case with downstream requirements that ingests a certain type and volume of data; include pros/cons and why each architecture piece was chosen over alternatives.
Asked in the Power Day system design stage. Candidate recommended a DB system, comparing OLAP versus OLTP, and discussed multi-region replication and failover. Clarify the use case, data contract, downstream ML requirements, scale, latency, consistency, retention, and recovery objectives before proposing an architecture.
