The DLZ users mailing list is pretty quiet, thought to ask here in
case someone can elaborate.
I have MySql query logging on so I can see the queries as they come in
for testing.
dig example.com @localhost
This yields a hit to the database of
090509 5:50:56 2593 Query SELECT zone FROM resource_records
WHERE zone = 'example.com'
2593 Query SELECT zone FROM resource_records WHERE zone =
'com'
Two hits.
dig a.b.c.d.f.g.h.i.j.k.l.m.n.o.p.q.r.s.t.u.v.w.x.y.z.example.com
@localhost A
Small snip of the log for that one, I am sure you get the idea:
2593 Query SELECT zone FROM resource_records WHERE zone =
's.t.u.v.w.x.y.z.example.com'
2593 Query SELECT zone FROM resource_records WHERE zone =
't.u.v.w.x.y.z.example.com'
2593 Query SELECT zone FROM resource_records WHERE zone =
'u.v.w.x.y.z.example.com'
2593 Query SELECT zone FROM resource_records WHERE zone =
'v.w.x.y.z.example.com'
2593 Query SELECT zone FROM resource_records WHERE zone =
'w.x.y.z.example.com'
2593 Query SELECT zone FROM resource_records WHERE zone =
'x.y.z.example.com'
2593 Query SELECT zone FROM resource_records WHERE zone =
'y.z.example.com'
2593 Query SELECT zone FROM resource_records WHERE zone =
'z.example.com'
2593 Query SELECT zone FROM resource_records WHERE zone =
'example.com'
2593 Query SELECT zone FROM resource_records WHERE zone = 'com'
Is this expected behavior? This seems quite a simple way to
potentially bring a data source to it's knees.
