Event Hub Store and Forward

The Event Hub Publisher block only has one option for store and forward functionality. As soon as a batch of input data is filled (to the maximum Event Hub publish request size) or the maximum batch interval (in the configuration file) has been reached, data will be stored in one of many disk-backed queues. The data is then popped off of these queues once it has been successfully published to Predix Event Hub. In the event of power loss, if some data has not been sent yet, it will still be available on disk, and the Cloud Gateway will pick up where it left off.
