S3 Select可以搜索多个对象吗? [英] Can S3 Select search multiple objects?

问题描述

我正在测试 S3 Select ，我从示例中了解到，您可以将单个对象(CSV或JSON)视为数据存储.

I'm testing out S3 Select and as far as I understand from the examples, you can treat a single object (CSV or JSON) as a data store.

我希望每个S3对象只有一个JSON文档，并将整个存储桶作为数据库"进行搜索.我将每个文件"另存为<ID>.json，每个文件都有具有相同架构的JSON文档.

I wanted to have a single JSON document per S3 object and search the entire bucket as a 'database'. I'm saving each 'file' as <ID>.json and each file has JSON documents with the same schema.

是否可以在单个调用中搜索多个对象?即找到所有JSON文档where customerId = 123?

Is it possible to search multiple objects in a single call? i.e. Find all JSON documents where customerId = 123 ?
