我正在使用 updateTable在 DynmaoDB 中，根据文档，如果我们要创建多个全局二级索引 (GSI)，我们需要在“GlobalSecondaryIndexUpdates”字段中有多个对象，因此我传递了以下参数，但它不会更新 GSI；但是，如果我只是创建一个 GSI(在“GlobalSecondaryIndexUpdates”字段中传递一个对象，它可以工作)；这是我为创建多个 GSI 而传递的参数:
{
"TableName": "movies",
"AttributeDefinitions": [{
"AttributeName": "id",
"AttributeType": "N"
}, {
"AttributeName": "title",
"AttributeType": "S"
}, {
"AttributeName": "subtitle",
"AttributeType": "S"
}],
"GlobalSecondaryIndexUpdates": [{
"Create": {
"IndexName": "title",
"ProvisionedThroughput": {
"ReadCapacityUnits": "5",
"WriteCapacityUnits": "5"
},
"KeySchema": [{
"AttributeName": "title",
"KeyType": "HASH"
}],
"Projection": {
"ProjectionType": "ALL"
}
}
}, {
"Create": {
"IndexName": "subtitle",
"ProvisionedThroughput": {
"ReadCapacityUnits": "5",
"WriteCapacityUnits": "5"
},
"KeySchema": [{
"AttributeName": "subtitle",
"KeyType": "HASH"
}],
"Projection": {
"ProjectionType": "ALL"
}
}
}]
}
我是否以错误的格式传递参数？
最佳答案
来自 DynamoDB documentation :
You can only create or delete one global secondary index per UpdateTable operation. However, if you run multiple UpdateTable operations simultaneously, you can create multiple indexes at a time. You can run up to five of these UpdateTable operations on a table at once, and each operation can create exactly one index.
