    • Query Optimization

      Index hinting can speed up specific queries, especially for queries which will return a lot of documents (120M+) out of a large dataset (3x avail RAM+).

      Index hinting is currently requested for the aggregation framework (SERVER-7944) but would speed up MapReduce jobs as well.
