A seasonal tax-appeal departmental app needs full relational SQL compatibility but sits nearly idle most months and spikes for a few weeks. Which database option best fits variable load without oversized always-on capacity?
Select an answer to reveal the explanation.
Short Explanation
Seasonal tax season is like a pop-up permit window—busy for weeks, quiet the rest of the year. Aurora Serverless v2 keeps the relational language you need and flexes capacity instead of renting a stadium all winter.
Full Explanation
Amazon Aurora Serverless v2 provides relational Aurora compatibility while scaling capacity with demand, which fits variable-load departmental applications. A perpetually oversized RDS instance wastes cost. S3 Select is not an OLTP database engine, and Neptune targets graph workloads rather than standard relational tax-appeal schemas.
