 In DynamoDB, keys consist of two parts: a *hash key* and a *range key*. To achieve LevelDB-like behaviour, all keys in a database instance are given the same hash key. That means that you can't do range queries over keys with different hash keys.
 
-The default hash key is `!`. You can specify it by putting a `/` in the `location` argument. The `/` separates the table name from the hash key.
