Dear Monks,

i come in shame as i have to admit that i use perl combined with mysql in a way that cant be right. At least it feels so wrong.
I've got an Application which is written in Perl embedded into Apache. I've got some fancy scripts which i call agents. Now : When there are certain things happening in Apache like i get an request from the outside world and i have the urge to tell it my mighty agent what i do is insert a string of JSON into a table which i call "do".

My Agent does something like this : 
while(1){
   foreach my $p (@{$dbh->selectall_arrayref(qq|SELECT id, do, ts FROM
+ do|, {Slice=>{} })}){
      # Do what the JSON is telling me 
   }

   sleep 1;
}

By now u know what i mean with it feels wrong in any possible way. So i started digging : Signals, Mysql Triggers, POE, Anyevent, IO:: and so forth. What would you do or maybe have done to implement something like that. Dont worry all i need is some direction which would be best and i will read from there but im overwhelmed by posibilitys without havein any Idea what would really work in production later which actually works ... not like Threads when i looked at them 7 Years ago ^^

Any guidence would be appreciated
