// requester already owns a topic with the specified name, that topic's ARN is
// returned without creating a new topic.

// The name of the topic you want to create.
//
// Constraints: Topic names must be made up of only uppercase and lowercase ASCII
// letters, numbers, underscores, and hyphens, and must be between 1 and 256
// characters long.
//
// For a FIFO (first-in-first-out) topic, the name must end with the .fifo suffix.
//
// This member is required.
Name *string
// A map of attributes with their corresponding values.
//
// The following lists the names, descriptions, and values of the special request
// parameters that the 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.
//
// - SignatureVersion – The signature version corresponds to the hashing
// algorithm used while creating the signature of the notifications, subscription
// confirmations, or unsubscribe confirmation messages sent by Amazon SNS. By
// default, SignatureVersion is set to 1 .
//
// - TracingConfig – Tracing mode of an Amazon SNS topic. By default
// TracingConfig is set to PassThrough , and the topic passes through the tracing
// header it receives from an Amazon SNS publisher to its subscriptions. If set to
// Active , Amazon SNS will vend X-Ray segment data to topic owner account if the
// sampled flag in the tracing header is true. This is only supported on standard
// topics.
//
// The following attribute applies only to [server-side encryption]:
//
// - 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]. For
// more examples, see [KeyId]in the Key Management Service API Reference.
//
// The following attributes apply only to [FIFO topics]:
//
// - ArchivePolicy – Adds or updates an inline policy document to archive
// messages stored in the specified Amazon SNS topic.
//
// - BeginningArchiveTime – The earliest starting point at which a message in the
// topic’s archive can be replayed from. This point in time is based on the
// configured message retention period set by the topic’s message archiving policy.
//
// - 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]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.
