12/// Amazon DynamoDB is a fully managed NoSQL database service
13///
14/// Amazon DynamoDB is a fully managed NoSQL database service that provides
15/// fast and predictable performance with seamless scalability. DynamoDB
16/// lets you offload the administrative burdens of operating and scaling a
17/// distributed database, so that you don't have to worry about hardware
18/// provisioning, setup and configuration, replication, software patching,
19/// or cluster scaling.
20///
21/// With DynamoDB, you can create database tables that can store and
22/// retrieve any amount of data, and serve any level of request traffic.
23/// You can scale up or scale down your tables' throughput capacity without
24/// downtime or performance degradation, and use the Amazon Web Services
25/// Management Console to monitor resource utilization and performance
26/// metrics.
27///
28/// DynamoDB automatically spreads the data and traffic for your tables
29/// over a sufficient number of servers to handle your throughput and
30/// storage requirements, while maintaining consistent and fast
31/// performance. All of your data is stored on solid state disks (SSDs) and
32/// automatically replicated across multiple Availability Zones in an
33/// Amazon Web Services Region, providing built-in high availability and
34/// data durability.
