예 1: 태그가 포함된 테이블을 생성하는 방법

다음 create-table 예시에서는 지정된 속성과 키 스키마를 사용하여 이름이 MusicCollection인 테이블을 생성합니다. 이 테이블은 프로비저닝된 처리량을 사용하며, 기본 AWS 소유 CMK를 사용하여 저장 시 암호화됩니다. 이 명령은 또한 키가 Owner이고 값이 blueTeam인 태그를 테이블에 적용합니다.

예 5: 글로벌 보조 인덱스가 있는 테이블을 생성하는 방법

다음 예시에서는 이름이 GameTitleIndex인 글로벌 보조 인덱스가 있는 GameScores라는 테이블을 생성합니다. 기본 테이블은 파티션 키가 UserId이고 정렬 키가 GameTitle이므로 특정 게임의 개별 사용자 최고 점수를 효율적으로 찾을 수 있는 반면 GSI는 파티션 키가 GameTitle이고 정렬 키가 TopScore이므로 특정 게임의 전체 최고 점수를 빠르게 찾을 수 있습니다.

aws dynamodb create-table \
    --table-name GameScores \

예 10: 삭제 방지가 활성화된 테이블을 생성하는 방법

다음 예시에서는 이름이 GameScores인 테이블을 생성하고 삭제 방지를 활성화합니다.

aws dynamodb create-table \
    --table-name GameScores \

    --key-schema AttributeName=UserId,KeyType=HASH AttributeName=GameTitle,KeyType=RANGE \
    --provisioned-throughput ReadCapacityUnits=10,WriteCapacityUnits=5 \
