Paginators for DynamoDB

import boto3

# Create your own session
my_session = boto3.session.Session(region_name="regionA", profile_name="profileA")
client = my_session.client('dynamodb')
paginator = client.get_paginator('scan')

# Option 1, paginate through paginator, a bit clunky, but possibly better performance
response_iterator = paginator.paginate(

)

for resp in response_iterator:
    for item in resp['Items']:
        print(f"{item['pk']}:{item['sk']}")

# Option 2: Build the full result, cleaner and allows for enumerator, but might need to store VAST data in memory
response_iterator = paginator.paginate(
    TableName="kl.Klayers-prodp38.db"
).build_full_result()

for k, item in enumerate(response_iterator['Items']):
