Defined in:

Overview

Simplifies working with Amazon DynamoDBStreams attribute values. Translates attribute values from responses to sensible Ruby natives.

This plugin is disabled by default for all Client objects. You can enable this plugin by passing simple_attributes: false to the client constructor:

ddb = Aws::DynamoDBStreams::Client.new(simple_attributes: true)

Output Examples

With this plugin enabled, simple_attributes: true:

resp = dynamodbstreams.get_records(shard_iterator: iterator)
resp.records.first.dynamodb.new_image
{
  id: 'uuid',
  enabled: true,
  tags: #<Set: {"attributes", "simple"}>,
  data: #<StringIO:0x00007fe4061e6bc0>,
  scores: [0.1e1, 0.2e1, 0.3e1, nil],
  name: {
    first: 'John',
    last: 'Doe',
  }
}

With this plugin disabled, simple_attributes: false:

resp = dynamodbstreams.get_records(shard_iterator: iterator)
resp.records.first.dynamodb.new_image
{
  "id"=> <struct s='uuid', n=nil, b=nil, ss=nil, ns=nil, bs=nil, m=nil, l=nil, null=nil, bool=nil>
  "enabled"=> <struct s=nil, n=nil, b=nil, ss=nil, ns=nil, bs=nil, m=nil, l=nil, null=nil, bool=true>
  ...
}
