MongoDB update

One pleasure in talking with my clients at MongoDB is that few things are NDA. So let’s start with some numbers:

Also >530 staff, and I think that number is a little out of date.

MongoDB lacks many capabilities RDBMS users take for granted. MongoDB 3.2, which I gather is slated for early November, narrows that gap, but only by a little. Features include:

There’s also a closed-source database introspection tool coming, currently codenamed MongoDB Scout. 

As for storage engines:

Finally — most data management vendors brag to me about how important their text search option is, although I’m not necessarily persuaded. 🙂 MongoDB does have built-in text search, of course, of which I can say:

This level of technology was easy to get in the 1990s. One thing that’s changed in the intervening decades, however, is that text search commonly supports more languages. MongoDB offers stemming in 8 or 9 languages for free, plus a paid option via Basis for other languages yet.

    MongoDB lacks some features more mature SQL solutions include, and many applications require. More mature SQL solutions lack features to make sharded replica sets easy to manage. Who gets there first? This will be an interesting race.

In other hand, data, which do not match the schema, will be missing in reports…

    Hi Curt, thanks for the post.

    One small clarification – your point about the performance of validation. For any DBMS I think it is a good idea and common practice to do some amount of validation client side – you shouldn’t round trip to the DBMS if you don’t have to.

    Fair enough, Kelly. But it does somewhat undermine the importance of the feature. 🙂

    […] MongoDB isn’t the only company I reached out to recently for an update. Another is DataStax. I chatted mainly with Patrick McFadin, somebody with whom I’ve had strong consulting relationships at a user and vendor both. But Rachel Pedreschi contributed the marvelous phrase “twinkling dashboard”. […]
