In that context, I’ll focus on C++ and try to: highlight what needs attention (what C++’s problem “is”), and how we can get there by building on solutions already underway; address some common misconceptions (what C++’s problem “isn’t”), including practical considerations of MSLs; and leave a call to action for programmers using all languages.

Based on this experience and learning, we built DynamoDB to be a fast, highly scalable NoSQL database to meet the needs of Internet-scale applications. These high-throughput, low-latency requirements need caching, not as a consideration, but as a best practice. DynamoDB was the first service at AWS to use SSD storage.
