The CloudFront create_invalidation API lets you specify a Quantity which seems redundant. Is there a use case for setting a Quantity different from the length of Items?
response = client.create_invalidation(
DistributionId = 'string',
InvalidationBatch = {
'Paths': {
'Quantity': 2,
'Items': [
'/index.html',
'/image.png',
]
},
'CallerReference': 'string'
}
)
The documentation says that the quantity field is required, and integer, and "The number of invalidation paths specified for the objects that you want to invalidate."
One usecase for supplying a smaller number than the number of items might be: sending more data than necessary to the AWS API.
A usecase for supplying a larger number might be: trying to trigger an error condition in the AWS API.
I would suggest just using the API as documented.
