I wonder, what does this mean for TokuMX
I wonder why 10gen hasn't made any official comment on the work the folks at Tokutek are doing to enhance Mongodb's features.
Why would they comment? What would they say? Toku is basically trying to steal MongoDB's customers, they even use the same basic pricing model.
We generally don't criticize indiscriminately. MongoDB has a lot of good sides and we embrace and extend those, and where it has faults we try to work around or replace them. Our core strength is fast, reliable, compressed storage and MVCC semantics, so obviously we talk about that a lot, but we also understand and acknowledge that a large amount of TokuMX's success, to the degree it has some, is due to the excellent parts of MongoDB.
As an example, I personally am really excited about what MongoDB has done with aggregations in 2.6 (and what seems to be coming down the pipe soon), and I can't wait to merge it in to TokuMX. We all get stronger together.
