 Description   

The server should log when a new shape is added to the query plan cache for a given collection.

The following operations on the query plan cache are currently logged at log level 1. We should consider adding these to QLOG and/or bubbling them up to log level 0 under certain (TBD) circumstances:

  • clearing the cache
  • changing the plan for a shape in the cache ("feedback")
  • evicting a shape from the cache

Since QLOG has been merged into the logging subsystem, these messages are now logged at log level 5 for the "query" log component. I no longer believe that there are clear circumstances under which these log messages should be bubbled up to log level 0. Closing this ticket as a dup of SERVER-17525.
