AWS Command Line Interface v2를 사용한 고급 DynamoDB 글로벌 보조 인덱스 시나리오 작업

여러 GSI가 있는 테이블을 생성합니다.

# Create a table with multiple GSIs
aws dynamodb create-table \
    --table-name MusicLibrary \
    --attribute-definitions \
        AttributeName=Artist,AttributeType=S \
        AttributeName=SongTitle,AttributeType=S \
        AttributeName=AlbumTitle,AttributeType=S \
        AttributeName=Genre,AttributeType=S \
        AttributeName=Year,AttributeType=N \
    --key-schema \
        AttributeName=Artist,KeyType=HASH \
        AttributeName=SongTitle,KeyType=RANGE \
    --billing-mode PAY_PER_REQUEST \
    --global-secondary-indexes \
        "[
            {
                \"IndexName\": \"AlbumIndex\",
                \"KeySchema\": [{\"AttributeName\":\"AlbumTitle\",\"KeyType\":\"HASH\"}],
                \"Projection\": {\"ProjectionType\":\"ALL\"}
            },
            {
                \"IndexName\": \"GenreYearIndex\",
                \"KeySchema\": [
                    {\"AttributeName\":\"Genre\",\"KeyType\":\"HASH\"},
                    {\"AttributeName\":\"Year\",\"KeyType\":\"RANGE\"}
                ],
                \"Projection\": {\"ProjectionType\":\"INCLUDE\",\"NonKeyAttributes\":[\"Artist\",\"SongTitle\"]}
            }
        ]"

온디맨드 용량과 GSI를 사용하여 테이블을 생성합니다.

# Create a table with on-demand capacity and GSI
aws dynamodb create-table \
    --table-name MusicOnDemand \
    --attribute-definitions \
        AttributeName=Artist,AttributeType=S \
        AttributeName=SongTitle,AttributeType=S \
        AttributeName=Genre,AttributeType=S \
    --key-schema \
        AttributeName=Artist,KeyType=HASH \
        AttributeName=SongTitle,KeyType=RANGE \
    --billing-mode PAY_PER_REQUEST \
    --global-secondary-indexes \
        "[
            {
                \"IndexName\": \"GenreIndex\",
                \"KeySchema\": [{\"AttributeName\":\"Genre\",\"KeyType\":\"HASH\"}],
                \"Projection\": {\"ProjectionType\":\"ALL\"}
            }
        ]"

여러 GSI가 있는 테이블에 항목을 넣습니다.

# Add items to MusicLibrary table
aws dynamodb put-item \
    --table-name MusicLibrary \
    --item '{
        "Artist": {"S": "The Beatles"},
        "SongTitle": {"S": "Hey Jude"},
        "AlbumTitle": {"S": "Past Masters"},
        "Genre": {"S": "Rock"},
        "Year": {"N": "1968"}
    }'

aws dynamodb put-item \
    --table-name MusicLibrary \
    --item '{
        "Artist": {"S": "Miles Davis"},
        "SongTitle": {"S": "So What"},
        "AlbumTitle": {"S": "Kind of Blue"},
        "Genre": {"S": "Jazz"},
        "Year": {"N": "1959"}
    }'

여러 GSI가 있는 테이블에서 항목을 쿼리합니다.

# Query the AlbumIndex GSI
echo "Querying AlbumIndex GSI:"
aws dynamodb query \
    --table-name MusicLibrary \
    --index-name AlbumIndex \
    --key-condition-expression "AlbumTitle = :album" \
    --expression-attribute-values '{":album":{"S":"Kind of Blue"}}'

# Query the GenreYearIndex GSI with a range condition
echo "Querying GenreYearIndex GSI with range condition:"
aws dynamodb query \
    --table-name MusicLibrary \
    --index-name GenreYearIndex \
    --key-condition-expression "Genre = :genre AND #yr > :year" \
    --expression-attribute-names '{"#yr": "Year"}' \
    --expression-attribute-values '{":genre":{"S":"Rock"},":year":{"N":"1965"}}'
