An ecommerce company has built a web application that uses an Amazon Aurora DB cluster. The DB cluster includes memory optimized instance types with both a writer node and a reader node. Traffic volume changes throughout the day. During sudden traffic surges, Amazon CloudWatch metrics for the DB cluster indicate high RAM consumption and an increase in select latency. A SysOps administrator must implement a configuration change to improve the performance of the DB cluster. The change must minimize downtime and must not result in the loss of data. Which change will meet these requirements?
