-----------------------
designate-pool-manager is a service that manages the states of the DNS servers Designate manages. The Pool Manager is configured to know which DNS servers Designate manages, and their type of backend (PowerDNS, BIND9, etc). It can also divide those servers into 'Pools' so that zones within Designate can be split across different sets of backend servers. The Pool Manager is also responsible for making sure that backend DNS servers are in sync with the Designate database.
