You are using IOT sensors to monitor the movement of a group of hikers on a three day trek and send the information into an Kinesis Stream. They each have a sensor in their shoe and you know for certain that there is no problem with mobile coverage so all the data is getting back to the stream. You have used default settings for the stream. At the end of the third day the data is sent to an S3 bucket. When you go to interpret the data in S3 there is only data for the last day and nothing for the first 2 days. Which of the following is the most probable cause of this?
