DynamoDB Error: Member must have length less than or equal to 2; Member must satisfy enum value set: [HASH, RANGE]

Question

我正在尝试在 DynamoDB 中创建底部显示的 table，但出现此错误。我知道您不能定义多个 PK，但是 GSI-PKs 也是这样吗？我该如何修复错误？

2 validation errors detected: Value '[KeySchemaElement(attributeName=VenueID, keyType=HASH), KeySchemaElement(attributeName=VenueName, keyType=Range), KeySchemaElement(attributeName=CheckInID, keyType=HASH)]' at 'globalSecondaryIndexes.1.member.keySchema' failed to satisfy constraint: Member must have length less than or equal to 2; 
Value 'Range' at 'globalSecondaryIndexes.1.member.keySchema.2.member.keyType' failed to satisfy constraint: Member must satisfy enum value set: [HASH, RANGE]

Answer 1

如果您需要两个属性的索引，请创建两个索引。一个 BeaconAddr-index 索引不能具有两个散列属性。

此外，我想知道您是否误解了什么，因为将索引命名为 BeaconAddr-index 而未在 BeaconAddr 上建立索引似乎很奇怪？你打算做什么？
