Support multiple configurations

[Chen-George-Zhen]

Support two or more aws configuration or specify configuration for model

Could you describe a case when this feature is needed?

Thank you, for example, in the same rails project, you need to connect two Amazon's DynamoDB, different access_key, secret_key, region

I see. Will add this feature request for the next minor release in 3-4 months.

So actually there are two options:

• to specify config options per model statically
• to specify it dynamically

Let's consider both options. I am still not sure whether we need only one of them or both.

Option #1

Let's consider an example:

class User
  include Dynamoid::Document

  configure do |config|
    config.access_key = 'REPLACE_WITH_ACCESS_KEY_ID'
    config.secret_key = 'REPLACE_WITH_SECRET_ACCESS_KEY'
    config.region = 'us-west-2'    
  end
end

Option #2

Consider another example:

class User
  include Dynamoid::Document
end

Dynamoid.configure(access_key: '', secret_key: '', region: '') do
  User.count
end

thank you very much！
Specifying configuration options for the model is more flexible，
If no configuration is specified, the default configuration is used.
This is my humble opinion

[pboling]

I agree, option 1 seems preferable.

[dgarciacity]

It would be very helpful, in my case I'm trying to use a different namespace for one model and it's not possible.

I'd love to see a per-model configuration as well. This helps when needing to deal with data that's sourced from multiple regions (and the source applications can't be housed in a single region).

[andrykonchin]

Will prioritize this task 👍 .
