I've been having trouble with congomongo for the reasons you specified, and a few more (doesn't sort, ran into a bug where limit was working properly with large datasets).
I recently switched to the "karras" clojure wrapper for mongodb (http://github.com/wilkes/karras), and found it to be much more fully-featured and reliable, and it works with the 2.2 mongo java driver and has no reflection warnings. Congomongo has a somewhat simper, more intuitive api, and the karras documentation is mostly non-existent (I figured it out primarily by reading the source files "collection" and "sugar"), but overall, I'm very glad I switched. I agree that mongodb fits well with Clojure and I intend to use it whenever possible. My only real negative issue with mongodb is that it has severe size constraints on a 32-bit platform. Sadly, for my current project, I hit a wall with mongo. After trying out couchDB, sqlite, h2, and a couple other options, I eventually settled on MySQL as the one that worked best to manipulate the quantity of data I need into the file and memory limitations of my machine. None of the options were anywhere near as fast or as easy to program as mongo, though. Almost makes me wish I were running a 64-bit OS. The only other Clojure/mongo "gotcha" I've experienced is that if you use Clojure's lazy sequences to stream through query results, and you do some sort of update on the objects in the query, it screws with the streaming query and the lazy stream can end up skipping over objects that fit the query. So it's vital to use doall to force the entire lazy stream to be realized before you do any updates. This is unfortunate, because it means you're memory bound if you want to update all the items in your database. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
