Delay on the Flexmatch events notifications to SNS topics

Question

We notice about 60 seconds delay between the server completing starting the game session and SNS receiving the FlexMatch event notifications. For example, the following image from the server log shows the server completed starting the game session at 03:42:21, however the SNS executed the lambda function at around 03:43:20.

Any suggestion or advice is greatly appreciated.

Hi, to better understand your issue, you should (if not done yet) configure the SNS  support to log the delivery status of notification messages sent to topics (Lambda is supported): see https://docs.aws.amazon.com/sns/latest/dg/sns-topic-attributes.html

It may be possible that you get the SNS notification only after some retries: see corresponding retry policies at https://docs.aws.amazon.com/sns/latest/dg/sns-message-delivery-retries.html

So, having the notification log messages will help you determining if you are in retry case and why or the other root cause.

Best,

Didier
