How to log throttling events with dynamodb

[RudolfVonKrugstein]

Hi,
As I understand it, boto3 does automatic exponential backoff when getting throttled by dynamodb.
That is fine and I dont want to change that behavior, but can I somehow log this trottling events? And/or detect these events after a call to i.E. dynamodb.get_item so that I can tell, how often the throtteling has happened?
Thanks!

If you have log level set to DEBUG then boto3 client should log retries or you can inspect the returned object and check the ResponseMetadata for the RetryAttempts count - https://boto3.amazonaws.com/v1/documentation/api/latest/guide/retries.html. Also you could monitor the cloudwatch metrics for throttles on your table.
