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"), // } // // See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-dynamodb-globaltable-keyschema.html // type CfnGlobalTable_KeySchemaProperty struct { // The name of a key attribute. // See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-dynamodb-globaltable-keyschema.html#cfn-dynamodb-globaltable-keyschema-attributename // 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. // See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-dynamodb-globaltable-keyschema.html#cfn-dynamodb-globaltable-keyschema-keytype // KeyType *string `field:"required" json:"keyType" yaml:"keyType"` }
