Quick Log Wipe?

Hello,

Firstly I would like to thank you for the creation of this plugin – the ease of use is awesome!

I would like to know if there is a safe way to wipe all redirection logs and all 404 logs recorded – I currently have over 250,000 404 logs recorded from recent bot crawling (several) and wordpress admin backend only allows me to show 200x at once for bulk delete, ultimately consuming a nice chunk of time – is there a safe db query I can run to clear all of these?

Thank you very much for your time and efforts!
