And the fact that you can run the indexing and visualization in separate passes is extremely useful, especially for E.g. large network file systems that are slow to index.

I like, I've been working on a faster parallel scanner written in go for the really large filesystems, in my env it's around 10x faster. In any case I find the scan -> database which the client can view quickly very useful.

Also note that there's text based, graphical, and web interfaces to view the database.
