ADVPERF04-BP02 Consider purpose-built and streaming databases

Purpose-built databases offer low latency and can better meet the scaling needs of advertising workloads.

Implementation guidance

Implement low-latency databases with in-memory AWS services (like Amazon DynamoDB or Apache Cassandra) or ISV products specialized for adtech (like Aerospike). 

Implement medium latency data stores with an OLTP database like Amazon Aurora Global Database to implement a multi-Region availability design.
