A lot of hype... And we still have db level locking. If document level is too difficult, at LEAST do collection level (not that it is too much better, but least it some real improvement).

"Finally, MongoDB 2.6 lays the foundation for massive improvements to concurrency in MongoDB 2.8, including document-level locking."

They hear you and are working on it.

Awesome news. I am excited for the aggregation cursor. As much as I love some of the alternatives that are almost ready I still turn to mongo for a vast majority of my deployments. Hopefully it will keep getting better and pushing others to do the same.

Playing with Meteor and mongo recently and have found mongo seems a little bit strange from a transitional SQL point of view, like do I need to embed or reference? Can anyone recommend a good book or source?

MongoDB Definitive Guide 2nd ed is pretty good

I don't know anything about MongoDB but can you give an example where DB level locking is a problem?

High volume of writes

I wonder, what does this mean for TokuMX

Am glad someone has brought up TokuMX. Tell me, have you used it in production yet? 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.

Cursor for aggregate, proper explain for aggregate, index intersection, $redact and other cool operators, Multi* in Geospatial, faster execution and, foundation for document-level locking which should be introduced in MongoDB 2.8. I must say I'm happy with this release.

Finally, MongoDB 2.6 lays the foundation for massive improvements to concurrency in MongoDB 2.8, including document-level locking. This is exciting even if I don't expect it to happen soon.

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