PowerDNS 4.7 Authoritative Server Brings Support for Catalog Zones
Improved LUA records, LMDB backend improvements, and support for Catalog Zones are among the new features in PowerDNS 4.7.
PowerDNS is a free and open-source authoritative DNS server that can be used in place of the standard BIND DNS server. It provides better performance while requiring less memory.
On top of that, PowerDNS has a significant advantage in that, in addition to the conventional basic zone files, it supports a wide range of backends such as MySQL, PostgreSQL, SQLite, LDAP, LMDB, and others.
The new just-released PowerdDNS 4.7 brings some improvements and new features, so let’s look at them.

Authoritative Server 4.7.0 | PowerDNS Blog
This is the release of version 4.7.0 of the Authoritative Server.
4.7.0 brings support for Catalog Zones, developed by Kees Monshouwer. As part of that development, the freshness checks in the Primary code were reworked, reducing them from doing potentially thousands of SQL queries (if you have thousands of domains) to only a few. Installations with lots of domains will benefit greatly from this, even without using catalog zones.
4.7.0 also brings back GSS-TSIG support, previously removed for quality reasons, now reworked with many stability improvements.
