Name *string

// CreateTopic action uses:
//
// * DeliveryPolicy – The policy that defines how Amazon
// SNS retries failed deliveries to HTTP/S endpoints.
//
// * DisplayName – The display
// name to use for a topic with SMS subscriptions.
//
// * FifoTopic – Set to true to
// create a FIFO topic.
//
// * Policy – The policy that defines who can access your
// topic. By default, only the topic owner can publish or subscribe to the
// topic.
//
// The following attribute applies only to server-side encryption
// (https://docs.aws.amazon.com/sns/latest/dg/sns-server-side-encryption.html):
//
// *
// KmsMasterKeyId – The ID of an Amazon Web Services managed customer master key
// (CMK) for Amazon SNS or a custom CMK. For more information, see Key Terms
// (https://docs.aws.amazon.com/sns/latest/dg/sns-server-side-encryption.html#sse-key-terms).
// For more examples, see KeyId
// (https://docs.aws.amazon.com/kms/latest/APIReference/API_DescribeKey.html#API_DescribeKey_RequestParameters)
// in the Key Management Service API Reference.
//
// The following attributes apply
// only to FIFO topics
// (https://docs.aws.amazon.com/sns/latest/dg/sns-fifo-topics.html):
//
// * FifoTopic –
// When this is set to true, a FIFO topic is created.
//
// * ContentBasedDeduplication
// – Enables content-based deduplication for FIFO topics.
//
// * By default,
// ContentBasedDeduplication is set to false. If you create a FIFO topic and this
// attribute is false, you must specify a value for the MessageDeduplicationId
// parameter for the Publish
// (https://docs.aws.amazon.com/sns/latest/api/API_Publish.html) action.
//
// * When
// you set ContentBasedDeduplication to true, Amazon SNS uses a SHA-256 hash to
// generate the MessageDeduplicationId using the body of the message (but not the
// attributes of the message). (Optional) To override the generated value, you can
// specify a value for the MessageDeduplicationId parameter for the Publish action.
