고객 정의 파티션 키 시작하기 - Amazon Timestream
차원 유형 파티션 키가 있는 테이블 생성

Amazon Timestream for LiveAnalytics와 유사한 기능을 원하는 경우 Amazon Timestream for InfluxDB를 고려해 보세요. 간소화된 데이터 수집과 실시간 분석을 위한 10밀리초 미만의 쿼리 응답 시간을 제공합니다. 여기에서 자세히 알아보세요.

고객 정의 파티션 키 시작하기

콘솔에서 테이블을 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

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