Based on my conversations with their CTO, 10gen (nee MongoDB Inc.) is philosophically against what Toku is up to in terms of indexing and optimization.

They're trying to generalize while Toku aims at very specific query optimization.

Interesting perspective, but it turns out that the opposite is true. Using better indexing is a general improvement to database performance and manageability.

His argument was that the indexing they do only improves a specific type of query. Personally I think he's wrong but that was his view a year or so ago.

I see. To clarify, TokuMX's indexing technology doesn't try to improve specific queries or patterns - it simply makes general index maintenance significantly cheaper and less space intensive, so your application can define the indexes it needs, not just the ones it can afford.
