AWS Command Line Interface v2 を使用して DynamoDB ローカルセカンダリインデックスを操作する

ローカルセカンダリインデックスを含むテーブルを作成します。

# Create a table with a Local Secondary Index
aws dynamodb create-table \
    --table-name CustomerOrders \
    --attribute-definitions \
        AttributeName=CustomerID,AttributeType=S \
        AttributeName=OrderID,AttributeType=S \
        AttributeName=OrderDate,AttributeType=S \
    --key-schema \
        AttributeName=CustomerID,KeyType=HASH \
        AttributeName=OrderID,KeyType=RANGE \
    --local-secondary-indexes \
        "IndexName=OrderDateIndex,\
        KeySchema=[{AttributeName=CustomerID,KeyType=HASH},{AttributeName=OrderDate,KeyType=RANGE}],\
        Projection={ProjectionType=ALL}" \
    --billing-mode PAY_PER_REQUEST

複数の LSI を含むテーブルを作成します。

# Create a table with multiple Local Secondary Indexes
aws dynamodb create-table \
    --table-name CustomerDetails \
    --attribute-definitions \
        AttributeName=CustomerID,AttributeType=S \
        AttributeName=Name,AttributeType=S \
        AttributeName=Email,AttributeType=S \
        AttributeName=RegistrationDate,AttributeType=S \
    --key-schema \
        AttributeName=CustomerID,KeyType=HASH \
        AttributeName=Name,KeyType=RANGE \
    --local-secondary-indexes \
        "[
            {
                \"IndexName\": \"EmailIndex\",
                \"KeySchema\": [
                    {\"AttributeName\":\"CustomerID\",\"KeyType\":\"HASH\"},
                    {\"AttributeName\":\"Email\",\"KeyType\":\"RANGE\"}
                ],
                \"Projection\": {\"ProjectionType\":\"INCLUDE\",\"NonKeyAttributes\":[\"Address\",\"Phone\"]}
            },
            {
                \"IndexName\": \"RegistrationIndex\",
                \"KeySchema\": [
                    {\"AttributeName\":\"CustomerID\",\"KeyType\":\"HASH\"},
                    {\"AttributeName\":\"RegistrationDate\",\"KeyType\":\"RANGE\"}
                ],
                \"Projection\": {\"ProjectionType\":\"KEYS_ONLY\"}
            }
        ]" \
    --billing-mode PAY_PER_REQUEST

LSI を使用してデータをクエリします。

# Query the OrderDateIndex LSI
aws dynamodb query \
    --table-name CustomerOrders \
    --index-name OrderDateIndex \
    --key-condition-expression "CustomerID = :custId AND OrderDate BETWEEN :date1 AND :date2" \
    --expression-attribute-values '{
        ":custId": {"S": "C1"},
        ":date1": {"S": "2023-01-01"},
        ":date2": {"S": "2023-02-01"}
    }'

# Query with a filter expression
aws dynamodb query \
    --table-name CustomerOrders \
    --index-name OrderDateIndex \
    --key-condition-expression "CustomerID = :custId" \
    --filter-expression "Amount > :amount" \
    --expression-attribute-values '{
        ":custId": {"S": "C1"},
        ":amount": {"N": "150"}
    }'
