Another "just out of curiosity" question. What sort of performance do
you see with BIND/DLZ/Postgres?
The http://bind-dlz.sourceforge.net/ site has some BIND-DLZ
performance test results listed. I don't know what version of BIND-9
they were using and I'm sure it is not current. With straight BIND-9
they were seeing 16,000 QPS, a reasonable number. With the Postgres
DLZ they saw less than 600 QPS. I'm sure that this performance can be
improved with fast hardware and (hopefully) a newer version of BIND.
With 50 million records, it would take about one day to perform a
single query for each of these records with the server doing nothing
else. It doesn't appear to me that you could serve this many records
using BIND-DLZ with Postgres in any environment that actually uses all
50 million RRs. Then again, at 16000 QPS, it would still take about
an hour to perform a single query for each of these 50 million records.
Granted, the startup/reload speed increase using DLZ will be
impressive, what I am questioning is having 50 million DNS resource
records on any DNS system. Is DNS an appropriate "database" for
storing 50 million records?

You can use mysql with dlz. I have yet to get it successfully
working, but that's another issue.
One of the reasons I wanted to use a database was for the speed
increase. I would probably look into using dlz.
