亚马逊网络服务DynamoDB SampleData:创建本地表

Question

AWS创建示例表

这是指向AWS Create Example Tables https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/SampleData.CreateTables.html的链接。我想为本地主机创建一个脚本，如下所示。我不知道如何使用create the Reply Table。有人能帮帮忙吗？

export LOCAL="--endpoint-url http://localhost:8000"

aws dynamodb create-table \
    $LOCAL \
    --table-name ProductCatalog \
    --attribute-definitions \
        AttributeName=Id,AttributeType=N
    --key-schema \
        AttributeName=Id,KeyType=HASH \
    --provisioned-throughput \
        ReadCapacityUnits=10,WriteCapacityUnits=5

aws dynamodb create-table \
    $LOCAL \
    --table-name Forum \
    --attribute-definitions \
        AttributeName=Name,AttributeType=S
    --key-schema \
        AttributeName=Name,KeyType=HASH \
    --provisioned-throughput \
        ReadCapacityUnits=10,WriteCapacityUnits=5


aws dynamodb create-table \
    $LOCAL \
    --table-name Thread \
    --attribute-definitions \
        AttributeName=ForumName,AttributeType=S \
        AttributeName=Subject,AttributeType=S \
    --key-schema \
        AttributeName=ForumName,KeyType=HASH \
        AttributeName=Subject,KeyType=HASH \
    --provisioned-throughput \
        ReadCapacityUnits=10,WriteCapacityUnits=5


aws dynamodb create-table \
    $LOCAL \
    --table-name Reply \
    --attribute-definitions \
        AttributeName=Id,AttributeType=S
        AttributeName=ReplyDateTime,AttributeType=S
    --key-schema \
        AttributeName=Id,KeyType=HASH \
        AttributeName=ReplyDateTime,KeyType=HASH \
    --provisioned-throughput \
        ReadCapacityUnits=10,WriteCapacityUnits=5

数据加载

对于从链接https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/SampleData.LoadData.html处的Step 2: Load Data into Tables复制过来的内容，这部分应该没问题

aws dynamodb batch-write-item --request-items file://ProductCatalog.json
aws dynamodb batch-write-item --request-items file://Forum.json
aws dynamodb batch-write-item --request-items file://Thread.json
aws dynamodb batch-write-item --request-items file://Reply.json

以下是运行正常的代码。

export LOCAL="--endpoint-url http://localhost:8000"

aws dynamodb delete-table $LOCAL \
    --table-name ProductCatalog

aws dynamodb create-table \

    --key-schema \
        AttributeName=Id,KeyType=HASH \
    --provisioned-throughput \
        ReadCapacityUnits=10,WriteCapacityUnits=5

aws dynamodb delete-table $LOCAL \
    --table-name Forum

aws dynamodb create-table \
    $LOCAL \
    --table-name Forum \
