Can't wait until they start implementing filtered indexes ( http://jira.mongodb.org/browse/SERVER-785 http://jira.mongodb.org/browse/SERVER-785 ). Sparse indexes are a step in the right direction, but filtered ones would be just a bit cooler :) "New map/reduce options for incremental updates" would also be really cool if they had a way to do something like couchDBs incremental views. This would require keeping track of changes or a "trigger" functionality that runs the m/r task after every x inserts
