/*
 * EventHubs bolt configurations
 *
 * Partition mode:
 * With partitionMode=true you need to create the same number of tasks as the number of 
 * EventHubs partitions, and each bolt task will only send data to one partition.
 * The partition ID is the task ID of the bolt.
 * 
 * Event format:
 * The formatter to convert tuple to bytes for EventHubs.
 * if null, the default format is common delimited tuple fields.
