如何将现有的发电机表架构导出到JSON？ [英] How to export an existing dynamo table schema to json?

问题描述

我想将一些动态表（仅模式）复制到我的本地环境中以进行测试。首先，我尝试过：

I'd like to replicate some dynamodb tables, schema only, into my local environment for testing purposes. First I've tried:

aws dynamodb describe-table --table-name Foo> FooTable.json

但是很明显，输出模式与 create-table中的输入模式不兼容命令：

But it's obvious that the output schema is not compliant to the input schema from the create-table command:

aws dynamodb create-table --cli-input-json文件：//FooTable.json- -endpoint = http：// localhost：8000

我要避免的是用<$ c $生成数十个骨架c> aws dynamodb create-table --generate-cli-skeleton 并手动填充它们：/

What I'm trying to avoid is to generate dozens of skeletons with aws dynamodb create-table --generate-cli-skeleton and fill them manually :/

有没有一种获取表的方法模式是否对娱乐有用？我觉得难以置信，没有任何简单的方法可以通过Web图形界面或标准的aws命令行来做到这一点-在听到他们的服务是多么好之后。

Is there a way to get the table schema in a format that is "useful" for recreation? I find it unbelievable that there are no straightforward way of doing it through the web graphic interface or the standard aws command line - after hearing how "good" was their service.

推荐答案

我刚刚使用 bchew / dynamodump 进行了一次完整的转储并还原：

I just managed to do a complete dump and "restore" using bchew/dynamodump:

git clone [e-mail]:bchew/dynamodump.git

请注意文档 https：// github中的-schemaOnly 选项。 .com / bchew / dynamodump 。命令是：

Notice the --schemaOnly option in the documentation https://github.com/bchew/dynamodump. Command was:

./dynamodump.py -m backup --schemaOnly --region foo-region --host localhost --srcTable '*' --port 8000 --accessKey fooKey --secretKey barKey

然后您可以使用 -m restore 模式可将数据或模式放回本地dynamodb或所需的任何地方：）

Then you can use the -m restore mode to put the data or schema back into a local dynamodb or wherever desired :)

说，我仍然感到难以置信的是亚马逊的dynamodb工具链有多糟糕。来吧，伙计们。

With that said, I still find it unbelievable how bad is the amazon dynamodb tool-chain. Come on guys.
