 Description   

These older commands are superseded by the new $planCacheStats aggregation metadata source implemented for 4.2 in SERVER-36528. They are inferior in that:

  1. They do not return a cursor.
  2. They do not permit projection, grouping, filtering, or other transformations using the full expressivity of the aggregation language.
  3. The 'planCacheListPlans' command displays its output in a less useful format than $planCacheStats.
