AWS config source pass supplementaryConfiguration data with resource

Is your feature request related to a problem? Please describe. Any reason why we do not return supplementaryConfiguration along with configuration . This would be helpful since this seems to contain tag information on resources which would be useful for further value filters.

Describe the solution you’d like We can either add it to the resource data by default , or can create an option on the config source that will then add it.

for example:

policies: 
  - name: sns-test
    resource: aws.sns
    source: config
    supplimentary-config: true
    query:  
      - clause:  "tags.key = 'tag-check'"

grep through the source for ConfigSource subclasses (there are at least a half-dozen) and do one for sns would be the recommend.

there are problems with resource group tagging that make it less then ideal for lambda usage. it needs api to get tags on a single resource, prioritizing as a feature request to your account team would be appreciated.
