SetTopicAttributesRequest

Empty constructor used to set properties independently even when a simple constructor is available

Instantiates SetTopicAttributesRequest with the parameterized properties

Gets and sets the property AttributeName.

A map of attributes with their corresponding values.

The following lists the names, descriptions, and values of the special request parameters that the SetTopicAttributes 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, email, and email-json subscriptions. For email and email-json subscriptions, the display name is used as the sender name for regular notification messages. Subscription confirmation and unsubscribe confirmation emails always use "Amazon Web Services Notifications" as the sender name.

• MaximumMessageSize – The maximum size, in bytes, of a message that can be published to the topic. Valid values are 1024 to 1048576 (1 MiB). The default is 262144 (256 KiB).

  A topic with a MaximumMessageSize above 256 KiB must have 100 or fewer subscriptions, and each subscription must be an Amazon SQS, Amazon Data Firehose, or Lambda subscription.

  You can increase or decrease this value at any time. If the topic doesn't meet these requirements when you set a value above 256 KiB, Amazon SNS returns an InvalidParameter error. For more information, see Large message payloads in the Amazon SNS Developer Guide.

• Policy – The policy that defines who can access your topic. By default, only the topic owner can publish or subscribe to the topic.

• 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.

• HTTP

  • HTTPSuccessFeedbackRoleArn – Indicates successful message delivery status for an Amazon SNS topic that is subscribed to an HTTP endpoint.

  • HTTPSuccessFeedbackSampleRate – Indicates percentage of successful messages to sample for an Amazon SNS topic that is subscribed to an HTTP endpoint.

  • HTTPFailureFeedbackRoleArn – Indicates failed message delivery status for an Amazon SNS topic that is subscribed to an HTTP endpoint.

• Amazon Data Firehose

  • FirehoseSuccessFeedbackRoleArn – Indicates successful message delivery status for an Amazon SNS topic that is subscribed to an Amazon Data Firehose endpoint.

  • FirehoseSuccessFeedbackSampleRate – Indicates percentage of successful messages to sample for an Amazon SNS topic that is subscribed to an Amazon Data Firehose endpoint.

  • FirehoseFailureFeedbackRoleArn – Indicates failed message delivery status for an Amazon SNS topic that is subscribed to an Amazon Data Firehose endpoint.

• Lambda

  • LambdaSuccessFeedbackRoleArn – Indicates successful message delivery status for an Amazon SNS topic that is subscribed to an Lambda endpoint.

  • LambdaSuccessFeedbackSampleRate – Indicates percentage of successful messages to sample for an Amazon SNS topic that is subscribed to an Lambda endpoint.

  • LambdaFailureFeedbackRoleArn – Indicates failed message delivery status for an Amazon SNS topic that is subscribed to an Lambda endpoint.

• Platform application endpoint

  • ApplicationSuccessFeedbackRoleArn – Indicates successful message delivery status for an Amazon SNS topic that is subscribed to an platform application endpoint.

  • ApplicationSuccessFeedbackSampleRate – Indicates percentage of successful messages to sample for an Amazon SNS topic that is subscribed to an platform application endpoint.

  • ApplicationFailureFeedbackRoleArn – Indicates failed message delivery status for an Amazon SNS topic that is subscribed to an platform application endpoint.

  In addition to being able to configure topic attributes for message delivery status of notification messages sent to Amazon SNS application endpoints, you can also configure application attributes for the delivery status of push notification messages sent to push notification services.

  For example, For more information, see Using Amazon SNS Application Attributes for Message Delivery Status.

• Amazon SQS

  • SQSSuccessFeedbackRoleArn – Indicates successful message delivery status for an Amazon SNS topic that is subscribed to an Amazon SQS endpoint.

  • SQSSuccessFeedbackSampleRate – Indicates percentage of successful messages to sample for an Amazon SNS topic that is subscribed to an Amazon SQS endpoint.

  • SQSFailureFeedbackRoleArn – Indicates failed message delivery status for an Amazon SNS topic that is subscribed to an Amazon SQS endpoint.

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.

• 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.

The following attribute applies only to FIFO topics:

• ArchivePolicy – The policy that sets the retention period for messages stored in the message archive of an Amazon SNS FIFO topic.

• 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.

• FifoThroughputScope – Enables higher throughput for your FIFO topic by adjusting the scope of deduplication. This attribute has two possible values:

  • Topic – The scope of message deduplication is across the entire topic. This is the default value and maintains existing behavior, with a maximum throughput of 3000 messages per second or 20MB per second, whichever comes first.

  • MessageGroup – The scope of deduplication is within each individual message group, which enables higher throughput per topic subject to regional quotas. For more information on quotas or to request an increase, see Amazon SNS service quotas in the Amazon Web Services General Reference.

Gets and sets the property AttributeValue.

The new value for the attribute.

Gets and sets the property TopicArn.

The ARN of the topic to modify.
