package awsdynamodb
// Represents *a single element* of a key schema.
//
// A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index.
//
// A `KeySchemaElement` represents exactly one attribute of the primary key. For example, a simple primary key would be represented by one `KeySchemaElement` (for the partition key). A composite primary key would require one `KeySchemaElement` for the partition key, and another `KeySchemaElement` for the sort key.
//
// A `KeySchemaElement` must be a scalar, top-level attribute (not a nested attribute). The data type must be one of String, Number, or Binary. The attribute cannot be nested within a List or a Map.
//
// Example:
// // The code below shows an example of how to instantiate this type.
// // The values are placeholders you should change.
// import "github.com/aws/aws-cdk-go/awscdk"
//
// keySchemaProperty := &keySchemaProperty{
// attributeName: jsii.String("attributeName"),
// keyType: jsii.String("keyType"),
// }
//
type CfnGlobalTable_KeySchemaProperty struct {
// The name of a key attribute.
AttributeName *string `field:"required" json:"attributeName" yaml:"attributeName"`
// The role that this 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's 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.
