Description of Linked Ticket
Right now when query results must be sorted before being returned, a top-N sort is performed in memory with a memory footprint cap enforced. The goal for this ticket is move to external sorting if too much memory is required, see discussion in SERVER-4716.
Scope of changes
- Document allowDiskUse parameter for find database command
- Document allowDiskUse() cursor method for db.collection.find()
- Document increase non-index sort memory cap (32MB -> 100MB)
Impact to Other Docs
- Drivers may need to either link to allowDiskUse or update their docs to reference support for the new option
