SNS: Port publish_batch to the Topic resource

[CharlesPerrotMinotHCHB]

Describe the feature

The SNS client has a public_batch to send a batch of notifications: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/sns/client/publish_batch.html

Notice that in a public_batch, all notifications are sent to one unique TopicArn. Unfortunately, the Topic resource does not have that method, only having publish supported: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/sns/topic/index.html

Use Case

Having a publish_batch method inside the Topic Resource would simplify code and the integration with the SNS Extended Client Library (https://github.com/awslabs/amazon-sns-python-extended-client-lib)

Hi @CharlesPerrotMinotHCHB thanks for reaching out. There is a feature freeze on boto3 resources as documented here: https://boto3.amazonaws.com/v1/documentation/api/latest/guide/resources.html

The AWS Python SDK team does not intend to add new features to the resources interface in boto3. Existing interfaces will continue to operate during boto3’s lifecycle. Customers can find access to newer service features through the client interface.

I will go ahead and close this issue for those reasons.

This is quite unfortunate, because resources have a different usage to clients, but thank you for taking the time.
