Example does not actually use sns_extended_client

[erlandsen-tech]

The library is imported, but then just shadowed further down in the code and will never be used.

import boto3
import sns_extended_client <--- This is imported here but never used

# Low level client
sns = boto3.client('sns')
sns.large_payload_support = 'bucket-name'

# boto SNS.Topic resource
resource = boto3.resource('sns')
topic = resource.Topic('topic-arn')
# rest of code omitted

The same goes for all the examples except the last one.

So just to provide a snippet that actually works; add this to your lambda handler:

import sns_extended_client
sns_extended_client_resource = sns_extended_client.SNSExtendedClientSession().resource(
    service_name="sns", region_name="eu-west-1"
)
topic = sns_extended_client_resource.Topic(TOPIC_ARN)
topic.large_payload_support = S3_EXTENDED_PAYLOAD_BUCKET

#... something something create json data or whatever ...

topic.publish(TopicArn=TOPIC_ARN, Message=json_data)

I wondered the same thing until I was trying it out and noticed that any other boto client returns as a SNSExtendedClient. It's patched on import: https://github.com/awslabs/amazon-sns-python-extended-client-lib/blob/main/src/sns_extended_client/__init__.py
