If the extension’s attempt to send APM data during this time interval is not successful, the extension queues back the data. Further attempts at sending the data are governed by an exponential backoff algorithm: data will be sent after a increasingly large grace period of 0, then circa 1, 4, 9, 16, 25 and 36 seconds, provided that the Lambda function execution is ongoing.
