The primary key that uniquely identifies each item in an Amazon DynamoDB table can be simple (a partition key only) or composite (a partition key combined with a sort key). You should design your application for uniform activity across all partition keys in the table and its secondary index...
Partition key: A simple primary key, composed of one attribute known as thepartition key. Attributes in DynamoDB are similar in many ways to fields or columns in other database systems. Partition key and sort key: Referred to as acomposite primary key, this type of key is composed of two...

Every table in DynamoDB has a schema which specifies if it has a simple partition key (for pure key-value lookups), or a partition key and sort key both (for more complex query patterns). You use these index keys when accessing items in the table: storing and ...
