## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_dynamodb as dynamodb } from 'aws-cdk-lib';
const schemaOptions: dynamodb.SchemaOptions = {
  partitionKey: {
    name: 'name',
    type: dynamodb.AttributeType.BINARY,
  },
  sortKey: {
    name: 'name',
    type: dynamodb.AttributeType.BINARY,
  },
};
```

## Properties

- `partitionKey`: [Attribute](/cdk/api/v2/docs/aws-cdk-lib.aws_dynamodb.Attribute.html) — Partition key attribute definition.

  **Default:** exactly one of `partitionKey` and `partitionKeys` must be specified.

  If a single field forms the partition key, you can use this field.  Use the
  `partitionKeys` field if the partition key is a multi-attribute key (consists of
  multiple fields).

- `sortKey`: [Attribute](/cdk/api/v2/docs/aws-cdk-lib.aws_dynamodb.Attribute.html) — Sort key attribute definition.

  **Default:** no sort key

  If a single field forms the sort key, you can use this field.  Use the
  `sortKeys` field if the sort key is a multi-attribute key (consists of multiple
  fields).
