 Description   

I couldn't find any page on either the wiki or new manual documenting cache pre-warming strategies. MongoDB 2.2 added the 'touch' command, so it would be helpful to include actual use cases and effects for replica/sharded environments.

Other strategies include:

  • Write a query which returns nothing but has to consider every document
  • Force an index into memory by using a hint() with the query
  • Use the explain() command to get an idea of how many index items or documents would need to be scanned for a given query
