Apparently it's not ACID compliant at this point in time.

  My first impression: Compressed Indexes, New Index structure that allows sequential I/O read/write to disk of indexes, making indexes cheap. Cheap indexes = many indexes = improved query performance.

    If that's the case, then this would be a much smaller improvement for DB's that can be stored entirely in-memory or on SSD, right? I think that most small db's are mostly in memory, and most large ones will be on SSD soon, so do you think that this will have a smaller impact on those use cases?

      For really large databases, SSDs aren't cost effective (think multi-terabyte). For the smaller sized databases, most will prefer a hybrid SSD-RAID solution(like Sun's storage appliances) for cost again. Toku is targeting the niche of people who 1. Don't give a damm about ACID. 2. Can't afford hybrid SSD solutions. Toku's indexing technology would be worthwhile at the higher end also, and people with multi-terabytes of information at that end usually use a database as a persistence backend rather than a ACID RDBMS. (think FACEBOOK or your-next-large-startup). Those with a need for ACID, are already running Oracle (which lacks this technology AFAIK). I sense an Oracle-buy-me exit strategy.

  ACID compliance is scheduled to be released later this year.
