https://blueprints.launchpad.net/designate/+spec/yadifa-dns-backend

Problem description

There are users or env that may want to use YADIFA as backend which is not supported by designate as of now.

Proposed change

YADIFA is a lightweight authoritative Name Server with DNSSEC capabilities. It has a simple configuration syntax and can handle more queries per second while maintaining one of the lowest memory footprints in the industry. YADIFA also has one of the fastest zone file load times ever recorded on a name server.

Functionality:
. authoritative name server . DNS UPDATE . DNS NOTIFY . AXFR . IXFR . full featured client (yadifa), which can be used to control the server . key management, including a tool to generate dnssec keys . multi-master support . support for other network models . detect and configure hyperthreading . support for openssl 1.1.0 API
Use Cases:
  1. Alternative for BIND and NSD for public TLD slave. - Clean Implementation - High query rate and portable. - RFC compliant: - . Authoritative - . DNSSEC support - . AXFR/IXFR (master and slave)
  2. Dynamic updates - Dynamic updated(including continuous signing) - Generic, extensible storage backend.
  3. Zone management - Dynamic zone provisioning.
  4. Recursive Nameserver - Recursion - Validation
