DynamoDB：扫描多个非关键属性 [英] DynamoDB: Scan on multiple non key attribute

问题描述

我正在将我的应用程序从mysql迁移到DynamoDB，我有一个表，其中根据某些条件匹配5个非关键属性。该表将有很多读取操作（扫描）

I am migrating my app from mysql to DynamoDB, I have a table where i match 5 non key attribute based on certain conditions. This table will have lots of read operations(scan)

问题：是否有任何我可以不必设计表的方式扫描表格

Question:Is there are any possible ways that i design a table in such a way that i don't have to scan the table

推荐答案

我相信最近宣布的全局二级索引是您所需要的。

I believe the recently announced Global Secondary Indexes is what you need.

与本地二级索引一样，查询时不能只有一个索引。

As with Local Secondary Indexes - you can't you have than one index when querying.

这意味着您可能必须移动一些该逻辑进入应用程序层。

This means you will probably have to move some of that logic into the application layer.
