OpenStack DNS as a Service - producer

Designate provides DNSaaS services for OpenStack. It provides a multi-tenant REST API for domain & record management. It is Integrated with Keystone for authentication, and provides a framework in place to integrate with Nova and Neutron notifications (for auto-generated records). Designate supports PowerDNS and Bind9 out of the box.

This package provides the producer service. It is a service that handles the invocation of long-running and potentially large jobs. Producer processes start work for an automatically assigned shard of the zones Designate manages. Shards are allocated based on the first three characters of the zone ID (a UUID field). The number of shards under management of a single producer process is equal to the total number of shards divided by the number of producer processes. This means the more producer processes are started, the less work is created at any one time.

The current implemented tasks in producer include emitting dns.zone.exists events for Ceilometer, purging deleted zones from database, polling secondary zones at their refresh intervals, generating delayed NOTIFY transactions, and invoking a periodic recovery of zones in an error state.
