[Dovecot] architecture to handle 1000 messages per second?

Yep don't use POP/IMAP to fetch messages.
Use a script as said Michael.

You can let Postfix handle the queue if there are more mails than
your script can process. Or write a script that handle his own queue
to avoid 'locking' postfix during delivery.

In all cases an architecture 'online' is better than 'polling' via
POP/IMAP...

For scalability you can use multiple MX and/or spawn multiples threads
on the delivery script.

Hope that helps.

Regards.
