Custom storage provider for RequestQueue?

It's probably a little out of the ordinary, but I'm building a crawler project that stores a pretty large pile of information in a database, rather than Crawlee's native KVS and DataSet. I'm curious if there are any examples of using alternative backends to store Crawlee's own datasets and request queue? If possible i'd love to consolidate the storage in one place, particularly since it would allow me to query and manage the request pool a bit easier…
