On the other hand, MongoDB uses indexes on the collection level and supports indexes on any field o r sub-field of the documents in a MongoDB collection. Using these three models will help us connect different databases in our application. I've seen a few suggestions that if you use solid-state drives (SSD), it makes memory less important.

Also, we should keep in mind that our field names in BSON are stored in the records (but not the index) so if we are under memory pressure they should be kept short. While Java garbage collection (GC) will, in theory, be as CPU/time efficient as unmanaged memory, it requires 5-10x as much memory to do so. Ops Manager Overview Describes Ops Manager.
