(CreateTableInput).KeySchema

Defined in github.com/aws/aws-sdk-go/service/dynamodb/api.go

Description

Specifies the attributes that make up the primary key for a table or an index. The attributes in KeySchema must also be defined in the AttributeDefinitions array. For more information, see Data Model (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DataModel.html) in the Amazon DynamoDB Developer Guide.

Each KeySchemaElement in the array is composed of:

AttributeName - The name of this key attribute.

KeyType - The role that the key attribute will assume:

HASH - partition key

RANGE - sort key

  The partition key of an item is also known as its hash attribute. The

term "hash attribute" derives from DynamoDB' usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

The sort key of an item is also known as its range attribute. The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

For a simple primary key (partition key), you must provide exactly one

element with a KeyType of HASH.

For a composite primary key (partition key and sort key), you must provide exactly two elements, in this order: The first element must have a KeyType of HASH, and the second element must have a KeyType of RANGE.

For more information, see Specifying the Primary Key (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/WorkingWithTables.html#WorkingWithTables.primary.key) in the Amazon DynamoDB Developer Guide.
