It may well work for some parts of it but there's actually two caching 
mechanisms in the backend of IXP Manager: Laravel and Doctrine ORM. The 
recommended and supported caching mechanism is memcahced which 'just 
works' for both.

More generally, databases are designed for persistent storage rather 
than temporary caching. IXP Manager isn't going to get more than a 
couple concurrent requests per second so the usual database limitations 
as a cache won't come into play but - as above - it's neither supported 
nor recommended by us and won't work for the Doctrine side.
