[Pdns-users] Adding library lua functions for lua records

[Michel Otte]

Hi Jason,

AFAIK only configuration data can be stored in separate records. You might
be able to use the Lua2 backend as an additional backend to achieve what
you want, but your question lacks details. Please also see:
https://blog.powerdns.com/2016/01/18/open-source-support-out-in-the-open

With that being said, a feature has just been implemented in the
development branch that allows you to globally include Lua scripts:
https://github.com/PowerDNS/pdns/issues/11676 . With some patience it will
trickle down to a stable release and of course you can already try it out.

With kind regards,
Michel Otte
