DynamoDB表-> CloudSearch ==域“ l”在域配置中不存在

Question

摘要

我有一个DynamoDB表，其中包含少于十个项目，我正在尝试使用CloudSearch编制索引。 CloudSearch索引器建议使用不存在的名为"l"的属性。这似乎是以某种方式从DynamoDB JSON“列表”键（该列表键存储列表对象数组，在我的情况下为所有字符串）中获取的。无论如何，即使我在索引字段配置时删除了此键，在文档上载时仍然会遇到以下硬错误：

{["Field "l" does not exist in domain configuration (near operation with index 3; document_id null)",""add" operation must contain at least one "field" (near operation with index 5; document_id null)",""add" operation must contain at least one "field" (near operation with index 7; document_id null)","Field "l" does not exist in domain configuration (near operation with index 11; document_id null)",""add" operation must contain at least one "field" (near operation with index 13; document_id null)",""add" operation must contain at least one "field" (near operation with index 15; document_id null)","Field "l" does not exist in domain configuration (near operation with index 19; document_id null)",""add" operation must contain at least one "field" (near operation with index 21; document_id null)",""add" operation must contain at least one "field" (near operation with index 23; document_id null)","Field "l" does not exist in domain configuration (near operation with index 27; document_id null)",""add" operation must contain at least one "field" (near operation with index 29; document_id null)",""add" operation must contain at least one "field" (near operation with index 31; document_id null)","Field "l" does not exist in domain configuration (near operation with index 35; document_id null)",""add" operation must contain at least one "field" (near operation with index 37; document_id null)",""add" operation must contain at least one "field" (near operation with index 39; document_id null)"] }

你好！我有一个DynamoDB表，其中包含少于十个项目，这些项目具有〜35个不同类型的属性（字符串，数字，字符串列表

和映射）。我正在尝试通过aws控制台gui用CloudSearch索引此表。当我进入索引字段配置页面时，我的大多数属性都会显示出来-列表中特别缺少。但是，索引器确实建议根据以下图像显示"l"：

我假设这是DynamoDB JSON列表密钥。我尝试过保留并删除此建议，然后继续创建搜索域。无论哪种方式，十分钟后，当我尝试上传文档时，都会出现上述错误。

我发现我的表格项目中的所有列表[[正在删除

都导致此"l"建议消失，并且最终按预期进行了文档上载。DynamoDB表项是通过api创建的（使用boto3的DynamoDB“ Table”接口，如下所示：

body = {}
# body is populated as a regular python dict
dynamodb = boto3.resource('dynamodb')
table = dynamodb.Table("table_name")
table.put_item(Item = body, ConditionExpression = 'attribute_not_exists(ds_name)')

[我当时想也许这里有一个极端的情况，我应该使用更明确的boto3 DynamoDB客户端界面来创建项目-但使用上述方法可以正常工作，并且在DynamoDB中该项目看起来是完全正确和正常的gui查看器（在树和文本模式下）以及api“ .get_item()”调用。

总结，我有一个DynamoDB表，其中包含少于十个我正在尝试使用CloudSearch索引的项目。 CloudSearch索引器建议使用不存在的名为“ l”的属性。这似乎是某种原因...

从AWS支持获得响应-截至撰写本文时，CloudSearch不支持list和map类型。有一个添加它们的公开请求，但是“何时支持它们尚无ETA”。建议的替代方法是使用String Set代替适合我的用例的字符串列表。
