Can I send batch message to AWS SNS

I am developing an application in which I need to send multiple events to SNS. Is there any way to send all the events in batch or do I need to send/ publish using a for-loop (I'm using Java) one by one to the SNS.

The publish() API call only sends one message.

You will need to loop through your data and call publish() for each message.

Thanks @John. Is there any way I can validate if the publish is successful. I can see the "PublishResponse" returns only the message id. Can I check the status and validate? – Favorable 10/1, 2020 at 5:23

Please check: Amazon SNS Topic Attributes for Message Delivery Status and Viewing Amazon CloudWatch Metrics docs.aws.amazon.com/sns/latest/dg/sns-topic-attributes.html or Logs for SMS Deliveries in the Amazon SNS Developer Guide docs.aws.amazon.com/sns/latest/dg/sms_stats_cloudwatch.html – Abstract 10/1, 2020 at 8:4

@Favorable publish is when you send the message into SNS. If you get a MessageId back, then the publish succeeded, otherwise there could be no MessageId. Or, you might be referring to verifying delivery which is the asynchronous hand-off to the subscriber(s) on the other side of the SNS topic. – Rademacher 11/1, 2020 at 2:7

@Michael-sqlbot You are right. I can always handle this on the receiver side as you said. If an SQS is subscribed to the SNS, I can verify if the SQS got the message. – Favorable 17/1, 2020 at 6:59

SNS now supports publishing a batch of messages!

You can publish a batch of 10 messages in a single request now. It reduces the cost of API requests by 90%.

Link has the Java code references of bulk publishing.

If you need to publish multiple events, then I suggest to use EventBridge instead of SNS. It might cost a little more but We can pass around 10 events/ API call using EventBridge PutEvents API.

You can specify upto 5 targets as Lambda, SQS, etc. It can connect to all the services the SNS can pass on to and more.
