There is a timeout time for aws-lambda, it will hang up after at most 300 seconds.
Here is little more about it. http://docs.aws.amazon.com/lambda/latest/dg/limits.html
you can use
context.getRemainingTimeInMillis(); which will return you remaining time of your lambda so you can flush your data. If this is intended to be run longer than five minutes, then you can implement some kind of grace-full shutdown and flush your data before that.
