My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

It is required for a database to execute this query efficiently, which typically applies for systems that implement range scans over primary keys. DBLog High Level Architecture.

By Werner Vogels on 18 January 2012 07:00 AM. Amazon DynamoDB offers low, predictable latencies at any scale. This architectural pattern was a response to the scaling challenges that had challenged Amazon.com through its first 5 years, when direct database access was one of the major bottlenecks in scaling and operating the business.

So when we launched in January 2012, we provided simple query functionality that used hash primary keys or composite primary keys (hash + range). Efficient Queries. Since then, we have been working on adding flexible querying. You saw the first iteration in April 2013 with the launch of Local Secondary Indexes (LSI).
