/**
 * This example measures the time it takes for an acknowledgment to arrive back
 * at the producer. For this example, the producer region has distributed-ack
 * scope while the consumer region has distributed-no-ack scope. The producer
 * takes a timestamp, puts an entry value, waits for the ACK, and compares the
 * current timestamp with the timestamp taken before the put. Please refer to
 * the quickstart guide for instructions on how to run this example.
