node.js - 仅没有范围的Nodejs DynamoDB CreateTable哈希返回ValidationException

Question

我正在尝试在 dynamodb 上创建一个表通过他们的 aws-sdk on nodejs .下面是我传递给 dynamodb.createTable 的参数:

{
    TableName: 'new_table',
    ProvisionedThroughput: {
        ReadCapacityUnits: 1,
        WriteCapacityUnits: 1
    },
    KeySchema: [
        {AttributeName: 'primary_key', KeyType: 'HASH'}
    ],
    AttributeDefinitions: [
        {AttributeName: 'primary_key', AttributeType: 'S'},
        {AttributeName: 'some_attribute', AttributeType: 'S'}
    ]
}

返回

ValidationException: One or more parameter values were invalid: Number of attributes in KeySchema does not exactly match number of attributes defined in AttributeDefinitions

我已经通过在“KeySchema”上添加“some_attribute”来解决这个问题，但我想要的是一个没有“范围”的“哈希”表。

已解决:创建表时，只需要指定 KeySchema 属性，而不是要放在表上的所有属性。所以在我的例子中，我只需要指定'primary_key'

{
    TableName: 'new_table',
    ProvisionedThroughput: {
        ReadCapacityUnits: 1,
        WriteCapacityUnits: 1
    },
    KeySchema: [
        {AttributeName: 'primary_key', KeyType: 'HASH'}
    ],
    AttributeDefinitions: [
        {AttributeName: 'primary_key', AttributeType: 'S'},
    ]
}
