amazon-web-services - AWS DynamoDB Local 使用 awscli 添加全局二级索引

Question

您好，我尝试执行以下命令以将全局二级索引添加到现有表中:

aws dynamodb update-table \
    --region eu-west-1 \
    --endpoint-url http://127.0.0.1:8000/ \
    --table-name ssib_dev_assetsTable \
    --attribute-definitions AttributeName=AssetGroup,AttributeType=S \
    --global-secondary-index-updates  \
    Create="{IndexName=gsi_group,KeySchema=[{AttributeName=AssetGroup,KeyType=HASH}],Projection={ProjectionType=ALL}}" \
    --provisioned-throughput ReadCapacityUnits=10,WriteCapacityUnits=10 \

+ 或 - 10 秒后，我得到以下响应，没有任何明确的错误消息。我用 https://hub.docker.com/r/cnadiminti/dynamodb-local/模拟我的数据库。

An error occurred (InternalFailure) when calling the UpdateTable operation (reached max retries: 9): The request processing has failed because of an unknown error, exception or failure.

参数 --global-secondary-index-updates 应该是一个有效的 JSON 字符串，但您的情况并非如此。它还缺少强制性 key ProvisionedThroughput。

https://docs.aws.amazon.com/cli/latest/reference/dynamodb/update-table.html

这里是:

aws dynamodb update-table \
    --region eu-west-1 \
    --endpoint-url http://127.0.0.1:8000 \
    --table-name ssib_dev_assetsTable \
    --attribute-definitions AttributeName=AssetGroup,AttributeType=S \
    --global-secondary-index-updates '[{"Create":{"IndexName":"gsi_group","KeySchema":[{"AttributeName":"AssetGroup","KeyType":"HASH"}],"Projection":{"ProjectionType":"ALL"},"ProvisionedThroughput":{"ReadCapacityUnits":5,"WriteCapacityUnits":5}}}]'

By the way, you should probably use the official image instead of some image by some random user docker user: https://hub.docker.com/r/amazon/dynamodb-local/
