Another thing to keep in mind is that not all systems are meant to be CP systems.

Your last question is a bit loaded with a bunch of "ifs", so let's unwind it. I don't know what MongoDB will "support" as far as other engines go. But assuming we, Tokutek, release…

Another engineer at Tokutek here. As you see, we are up to 2.4, and have been investigating 2.6 and Geo. With all possible features, whether they be from MongoDB 2.6 or things we i…

Not for single-server performance. The database level lock severely limits MongoDB's single server performance. Just look up the sysbench benchmark comparing MongoDB with TokuMX (w…

TokuMX does have MVCC

TokuMX, which I work on, has document level locking and compression right now.

(I work for Tokutek) Write concurrecy: yes, TokuMX does not have a database level reader/writer lock. Index Building: yes, fractal trees can write data much more efficiently, so if…

ddorian, Can you elaborate what that means?

Roger, I work at Tokutek (and wrote the post above). I'm sorry you ran into issues trying out TokuMX. I assure you, we are "ready", as we have users running in production. Neverthe…

MongoDB 2.2 and 2.4

Just as in our TokuDB for MySQL product, we have zlib and lzma compression available.

Staying up to date is not an all-or-none proposition. We use feedback to drive direction. For example, even though we used 2.2 as a base, user feedback compelled us to include hash…

I work for Tokutek. Slava, thanks for the kind words. Just to clear up any possible confusion, this is the product. We release and support TokuMX. The research started roughly a ye…

From Leif earlier, "TokuMX offers multi-document transactional semantics without application changes (snapshot reads), as well as protocol support for multi-statement (read-modify-…

TokuMX was forked from 2.2.4, but we have and will continue to add features from 2.4. For instance, hash based sharding is in TokuMX. One cannot mix a replica set with TokuMX and M…

I work for Tokutek. In addition to performance improvements and compression, another cool thing about TokuMX: it's fully transactional. We hope this makes development of applicatio…

Hope this helps, from Tokutek's website: http://www.tokutek.com/solutions/

One big differentiating feature between TokuDB and other write optimized databases is that TokuDB is fully transactional, it is ACID compliant. There is a demand for this. AFAIK, T…
