      Description

      IndexSpec::getKeys() finds the set of index keys for a given document and index key spec. It's used when inserting / updating / deleting a document to update the index entries, and also for performing in memory sorts, deduping $or clauses and for other purposes.

      Right now extracting 10k elements from a nested object field within an array takes on the order of seconds on a decently fast machine. We could see how much we can optimize the implementation.
