add MessageAttributes for SNS filter policy

[tomoyamachi]

I want to use the SNS filter policy to send an email when the scanner finds malware.
https://docs.amazonaws.cn/en_us/sns/latest/dg/sns-subscription-filter-policies.html

Is it possible to add some MessageAttributes when publishing to SNS, which is used by the lambda function to tag s3 buckets?

examples:

   "MessageAttributes": {
      "scanner_status": {
         "Type": "Number",
         "Value": 0
      },
      "malware_count": {
         "Type": "Number",
         "Value": 1
      },
      "bucket_name": {
         "Type": "String",
         "Value":"s3://bucket_url"
      }
   }

I checked aws-python-email-notification, but this script needs to activate AWS SES and Lambda.

Hi @tomoyamachi ,
Sorry to reply you this late as we didn't get the notification properly.
The message attributes is currently not supported and we will document this feature request. To workaround this for now, you could write a Lambda function to filter the events first and send to another SNS topic that has the email subscription.

@carpusherw should we leave this issue open or maybe move to the Discussions under Ideas?

What are your thoughts on that?

[carpusherw]

@felipecosta09 Depends on what you want to discuss. Or you simply want to group all feature requests? If it's the later, I don't have a preference. We should accept all ways of reporting the requests and as long as PM is aware, or had been aware 😂.

Hi @tomoyamachi, AWS just announced the support for payload-based message filtering, which might just fit your need.
