I would not bet on this ;-) However, while ORDER is usually a very "bad"

small.

Will work as expected. Cleanup took 4 entire days 'til being finished
on the last slave before using partitions. Now it takes just some
seconds :-
ction when comparing
values.
If running a large DB you should definitively change column types, as
using string functions in your WHERE statements is seldom a good idea
(performance-wise).

Nonetheless I cannot immagine any special case where this DSNs (in case

suppressing them.

To accomplish what you are suggesting it should IMO suffice to "replace"
penpals_find() (is it possible to do so?) with some custom code reading
from Memcache - plusadding something int before_send(), storing
penpal-information.

That's all so far. I'm pretty sure I've forgotten something - but I'm

You can't create table quarantine referencing table msgs as long as msgs
