TokuDB is great technology, glad to see them embracing open source. Too bad their wordpress installation needs some tuning!

The site is down. What is great in this technology ?

For starters, it totally changes the database performance paradigm for managing tables with many indexes.

Sadly, we don't use TokuDB to run our web site. It's some relatively inexpensive service.

The main technical underpinning (though note this isn't my area) seems to be basing indices on a particular improvement to B-trees, Cache-Oblivious Streaming B-Trees, which have some nice performance characteristics. I think what TokuDB calls "fractal trees" are just a catchier synonym.

Here's an academic paper from a few years ago from some of the people involved: http://supertech.csail.mit.edu/papers/sbtree.pdf

And a more recent talk focused on TokuDB: http://www.bnl.gov/csc/seminars/abstracts/Bender_Presentatio...

OK, we are all learning first hand here about the "slashdot" effect http://en.wikipedia.org/wiki/Slashdot_effect (now Hacker news effect).

We are working to get the site back up (a simple Wordpress site set up by the marketing department that does not use our database). In the meantime, please take a look at http://mwne.ws/124r2GL

Thanks for all the comments. We clearly didn't anticipate this level of excitement, but are grateful for the interest.
