#set($rawAPIDataLength = $rawAPIData.length() - 1)
#set($rawAPIData = $rawAPIData.substring(1, $rawAPIDataLength))

Scalability is handled for you, and data is replicated across multiple availability zones automatically. Amazon handles all of the pain points associated with managing a distributed datastore for you, including replication, load balancing, provisioning, and backups.

Keys (Amazon calls them primary keys) can be composed of one attribute, called a hash key, or a compound key called the hash and range key. The key is used to uniquely identify an item in a table. The choice of the primary key is particularl
