I've got an application that creates work and posts the work requests
to a table. Each work request is just a single row in the table.
I've also got two systems that do the work based on the requests in
the table.
It seems that ideally, I could use the LISTEN/NOTIFY features to tell
the consumers when there is work. However, what I really need is a
blocking LISTEN. That is, it just sits there until it gets a NOTIFY.
Right now, the consumer checks for work every so often, and most of
the time finds none.
What's the best way to implement such a thing in Perl? Is there a
blocking LISTEN?
