# 고객 정의 파티션 키 시작하기
<a name="customer-defined-partition-keys-getting-started"></a>

콘솔에서 **테이블**을 선택하고 새 테이블을 생성합니다. 또한 SDK를 사용해서 `CreateTable` 작업에 액세스하여 고객 정의 파티션 키를 포함할 수 있는 새 테이블을 생성할 수 있습니다.

## 차원 유형 파티션 키가 있는 테이블 생성
<a name="code-samples.create-table-with-dimension-type-partition-key"></a>

다음 코드 조각을 사용하여 차원 유형 파티션 키가 있는 테이블을 생성할 수 있습니다.
