Casbah integrates a Scala toolkit layer on top of the official MongoDB Java driver.

Casbah is end-of-life (EOL):

Users are encouraged to migrate to the Mongo Scala Driver for a modern idiomatic MongoDB Scala driver.

Casbah is a Scala toolkit for MongoDB. We use the term “toolkit” rather than “driver”, as Casbah integrates a layer on top of the official mongo-java-driver for better integration with Scala. This is as opposed to a native implementation of the Mongo Wire Protocol, which the Java driver does exceptionally well. Rather than a complete rewrite, Casbah uses implicits and Pimp My Library code to enhance the existing Java code with fluid, Scala-friendly syntax.

How can I do a nested and/or query in casbah? For example: val q = $and( "a"->"b", $or("e"->"f", "e"->"g"), $or("c"->"d", "c"->"e") ) This sample doesn't compile, but that's the idea I'm trying to achieve.

Do we have some way to mark index with expireAfterSeconds property as infinite. I want to do this in order not to be forced to drop index later, and just change TTL using collMod. Or maybe we have some maximum value for expireAfterSeconds property?…
