[Pdns-users] potential side effects of ALIAS records

I wonder if there are any potential side effects if I enable ALIAS
support on my authoritative servers.

- Will outstanding recursion somehow block or slow down the answering of
normal ressource records?

- Will the expanded ALIAS result locally cached? (besides the packet
cache, e.g. based on TTL or is it the job of the resolver to cache)

- IS it correct that ALIAS is not activated unless I explicitly
configure "recursor=..."?

- If ALIAS is not enabled, will PDNS just ignore these records?

Any other things I need to know? I am a bit concerned doing potential
time consuming activities on my name servers.
