This parameter appears to control how often the apply launcher starts new workers. If it starts new workers in a loop iteration, it updates its last_start_time variable, and it won't start any more workers until another wal_retrieve_retry_interval has elapsed. If no new workers need to be started, it only wakes up every 3 minutes. -- Nathan Bossart Amazon Web Services: https://aws.amazon.com
