You cannot"warm up" the item cache by performing a Scan operation,because the item cache and query cache are separate entities.
Your application should consider the TTL value for the query cache, and how long your application is able to tolerate inconsistent results between the query cache and the item cache. .
When an application sends a Query or Scan request,DAX attempts to read a matching result set from the query cache using the specified parameter values.
If there are no matching items in the result set,then DAX stores an empty result set in the query cache, and returns the empty result set to the application.
